Selenium Chrome webdriver SessionNotCreatedException - java

Using selenium & Chrome webdriver, I'm getting below exception on trying to launch. I have gone through lot of posts and tried all possible ways.
I'm using compatible chrome browser and chrome drivers versions -
Version 80.
Java - 1.8
Windows 10 os
The same test when i run on my personal computer, its working. But it's giving below error on my organization s machine. Also, no issues if I use edge drivers.
org.openqa.selenium.SessionNotCreatedException: session not created
disconnected: unable to send message to renderer
Any thoughts to solve this?

Check for chromedriver version in organization's machine. Please update your chromedriver with lastest version in organization machine. Issue will get resolve

The ChromeDriver Version you are using in your code might be different than the Chrome Browser installed in your system.
Check and download the same version of driver as of your browser version.

You need to use the matching ChromeDriver (matching MAX number) with respect to the installed google-chrome version installed in your system.
As an example if you are using the current chrome=88.0.4324.104 effectively you can use either of the following versions of ChromeDriver:
ChromeDriver 88.0.4324.27
ChromeDriver 88.0.4324.96

Exception in thread "main" Session not created: This version of ChromeDriver only supports Chrome version 81 [duplicate]

I am currently new to robot framework.I am currently using latest window version of chrome and chromedriver which is 80 but when i try to run the test it gives the message "SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81" in pycharm but currently beta version of 81 is only available. I have tried uninstalling everthing and reinstalling it again but nothing works can anyone help me with this.Thank you!
Screenshots below:
I solved these kinds of problems using the webdrive manager.
You can automatically use the correct chromedriver by using the webdrive-manager.
Install the webdrive-manager:
pip install webdriver-manager
Then use the driver in python as follows
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
This answer is taken from https://stackoverflow.com/a/52878725
Do below steps :
Check the version of chrome browser.
download chromedriver of same version from https://sites.google.com/chromium.org/driver/home
Give correct path in the pycharm and run the code.
I got the same message on MacOS:
"selenium.common.exceptions.SessionNotCreatedException: Message:
session not created: This version of ChromeDriver only supports Chrome
version 81"
Then I run this command, it's gone:
# Homebrew 3
brew upgrade chromedriver
# Homebrew < 3
brew cask upgrade chromedriver
This error message...
SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81
...implies that the ChromeDriver v81 was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser where is version is other then 81.0.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You mentioned about using chromedriver=80 and chrome=80 but somehow while your program execution ChromeDriver v 81.0 is used.
So, it's quite evident your have chromedriver=81.0 present within your system and is present within the system PATH variable which gets invoked while you:
driver = webdriver.Chrome()
Solution
There are two solutions:
Either you upgrade chrome to Chrome Version 81.0 level. (as per ChromeDriver v81.0 release notes)
Or you can override the default chromedriver v81.0 binary location with chromedriver v80.0 binary location as follows:
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')

First of all check latest Chrome version (This is your browser Chrome version) link
Download same version of Chrome Web Driver from this link
Do not download latest Chrome Web Driver if it does not match your Chrome Browser version.
Note: When I write this message, latest Chrome Browser version is 84 but latest Chrome Driver version is 85. I am using Chrome Driver version 84 so that Chrome Driver and Chrome Browser versions are the same.
Go to your Chrome settings -> About Chrome -> Check version
and download chromedriver from Below according to your Chrome version
https://chromedriver.chromium.org/downloads
this works for me
brew cask upgrade chromedriver
Above is deprecated on MacOs, use:
brew install chromedriver (if not already installed)
brew upgrade chromedriver
Chrome version is updating everyday so you need use exact chromedriver version according chrome version
https://chromedriver.chromium.org/downloads in this website you can download chromedrivers
The solution (at least on OSX) is:
Download the latest chromedriver file.
Unzip the downloaded file.
Search the location of the old chromedriver file on your computer and replace it with the new chromedriver file.
Right-click the chromedriver file and click open. Do not double click as Mac will not open it the proper way.
Once the file runs for the first time, you can close it and the update will have taken place.
Your Chrome Driver version needs to match your Chrome Browser version
Get you Chrome Browser version, by typing chrome://version
enter image description here
Download Chrome Driver version that matches you Chrome Browser version, form this website
https://chromedriver.chromium.org/downloads
If you are getting this error when you run stuffs on automated cluster and you are downloading the stable version of the google chrome every time then you can use the below shell script to download the compatible version of the chrome driver dynamically every time even if the stable version of the chrome gets updated.
%sh
#downloading compatible chrome driver version
#getting the current chrome browser version
**chromeVersion=$(google-chrome --product-version)**
#getting the major version value from the full version
**chromeMajorVersion=${chromeVersion%%.*}**
# setting the base url for getting the release url for the chrome driver
**baseDriverLatestReleaseURL=https://chromedriver.storage.googleapis.com/LATEST_RELEASE_**
#creating the latest release driver url based on the major version of the chrome
**latestDriverReleaseURL=$baseDriverLatestReleaseURL$chromeMajorVersion**
**echo $latestDriverReleaseURL**
#file name of the file that gets downloaded which would contain the full version of the chrome driver to download
**latestDriverVersionFileName="LATEST_RELEASE_"$chromeMajorVersion**
#downloading the file that would contain the full release version compatible with the major release of the chrome browser version
**wget $latestDriverReleaseURL**
#reading the file to get the version of the chrome driver that we should download
**latestFullDriverVersion=$(cat $latestDriverVersionFileName)**
**echo $latestFullDriverVersion**
#creating the final URL by passing the compatible version of the chrome driver that we should download
**finalURL="https://chromedriver.storage.googleapis.com/"$latestFullDriverVersion"/chromedriver_linux64.zip"**
**echo $finalURL**
**wget $finalURL**
I was able to get the compatible version of chrome browser and chrome driver using the above approach when running scheduled job on the databricks environment and it worked like a charm without any issues.
Hope it helps others in one way or other.
With Laravel (PHP) you can fix this with:
php artisan dusk:install
It will download and install the new driver.
Documentation: https://laravel.com/docs/9.x/dusk#installation
The case when your Chrome is in the middle of its update also causes this exception. In my case chromedriver was already updated, while the chrome itself was v81 instead of v83.
You can also download the correct chromedriver version from:
https://chromedriver.chromium.org/downloads
https://chromedriver.storage.googleapis.com/index.html?path=81.0.4044.138/
I too had a similar problem. And I've got a solution .. Download the matching chromedriver, and place the chromedriver under the /usr/local/bin path. It works.
The way I solved this issue was quite simple, I checked my chrome version and I had an older chromedriver in my PATH variable, so I downloaded the chromedriver version that matched my browser and replaced the old one in the PATH, so when the webdriver module looked for a chromedriver in my PATH, it would find the matching version
I had already been running a local server at the same port the session wanted to run on, and this caused the error. Shutting down that local server fixed this for me.
You need to install webdriver manager. Make sure webdriver manager it is also updated.
If you use npm:
npm install -g webdriver-manager
webdriver-manager update
If you're getting this error in Visual Studio 2019 and using Selenium.WebDriver.ChromeDriver by jsakamoto, check the version you're referencing in the packages.config file.
<package id="Selenium.WebDriver.ChromeDriver" version="89.0.4389.2300" targetFramework="net45" />
Update your NuGet package to the appropriate version and resolve the issue.
I resolved this issue by simply running Firefox (geckodriver) instead of Chrome:
rsDriver(browser = "firefox")
I got this error after a recent chrome upgrade, and also I recently updated my Mac to Big Sur. Seems cask is not part of brew command, need to use it separately.
brew install --cask chromedriver
You can handle this exception
from selenium.common.exceptions import SessionNotCreatedException
Add this function
def update_chrome():
try:
print("Updating chrome driver")
download_chrome = "wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb"
unpack_chrome = "sudo dpkg -i google-chrome-stable_current_amd64.deb"
install_chrome = "sudo apt-get -f install"
file_path = os.path.join(os.environ['HOME'], "google-chrome-stable_current_amd64.deb")
if os.path.isfile(file_path):
print("{} found\nremoving {}".format(file_path, file_path))
os.remove(file_path)
else:
print("File does not exist {}".format(file_path))
old_chrome_ver = os.popen("/usr/bin/google-chrome --version").read().strip('Google Chrome ').strip().split(".")[0]
print("Current Chrome version: {}".format(old_chrome_ver))
os.system(command=download_chrome)
sleep(2)
os.system(command=unpack_chrome)
sleep(5)
os.system(command=install_chrome)
crnt_chrome_ver = os.popen("/usr/bin/google-chrome --version").read().strip('Google Chrome ').strip().split(".")[0]
print("Current Chrome version: {}".format(crnt_chrome_ver))
if crnt_chrome_ver == old_chrome_ver:
print("Chrome version is same as before")
elif crnt_chrome_ver > old_chrome_ver:
print("Chrome version is updated from {} to {}".format(old_chrome_ver, crnt_chrome_ver))
return True
except Exception as e:
print("Error while updating chrome: {}".format(e))
return False
then call this function
try:
# Your code here
except SessionNotCreatedException as snce:
print("Session not created: {}".format(snce))
chrome_update_result = False
if recurrences == 0:
chrome_update_result = update_chrome()
if chrome_update_result:
recurrences += 1
print("Chrome updated successfully")
erisapedia_bot(state, download_dir)
return True
else:
print("Chrome update failed")
return False
What worked for me is this command:
pip install chromedriver-binary==your_chrome_version
This will uninstall the current chrome-driver that you have installed and will install a chrome-driver that matches your chrome version.
The solution is:-
Check out the chrome version of your chrome.From chrome://settings/help
Check out which version of ChromeDriver is compatible with your current
chrome version from here
download the compatible one and replace the existing ChromeDriver with
a new ChromeDriver.
Now run the code
It didn't feel like folks were answering the issue here which is: being on the latest version of beta Chrome/Chromium and not seeing the matching chromedriver version
For example, currently as of writing this, Chromium for Mac is Version 86.0.4190.0 (Developer Build) (64-bit) however the latest chromedriver versions listed are
Current stable release: ChromeDriver 83.0.4103.39
Current beta release: ChromeDriver 84.0.4147.30
If you go to https://chromedriver.chromium.org/downloads/version-selection, they provide some pointers on getting a compatible version. One of the last lines near the end mentions trying the ChromeDriver Canary build which leads to how to get it from Chromium browser snapshots.
Of course this goes without saying that using the latest experimental version is likely to have bugs
I faced this problem even after using webdriver manager. I was able to resolve the issue after specifying the exact version of chromedriver that I needed in the webddriver manager.
I was using chrome version 84 and the webdriver manager was installing the latest version of chromedriver, which was 85.0.4183.38.
I made webdriver manager to open the chromedriver version 84.0.4147.30 by writing the following command.
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager(84.0.4147.30).install())
Referring to #dylanvanw answer. You might still out of luck. I found that you might have a different path that you have installed Python. In my case, I have to move Chromedriver.exe from the cache path (C:\Users\Poom.wdm\drivers\chromedriver\win32\84.0.4147.30) to C:\Python38 then it work!
Steps I took to make it work
Check your current Chrome version e.g. 81
Goto tools/nuget package manager
Select selenium chrome driver
upgrade/downgrade to the same Chrome-version you have.
Restarting the application should work.
I found a workaround to download latest version of ChromeDriver via WebDriverManager
You could try something like,
WebDriver driver = null ;
boolean oldVersion = true;
String chromeVersion = "";
try {
try{
FileReader reader = new FileReader("chromeVersion.txt") ;
BufferedReader br = new BufferedReader(reader) ;
String line;
while ((line = br.readLine()) != null){
chromeVersion = line.trim();
}
reader.close();
} catch (IOException e ) {}
WebDriverManager.chromedriver().version(chromeVersion).setup();
driver = new ChromeDriver() ;
} catch (Exception e) {
oldVersion = false;
String err = e.getMessage() ;
chromeVersion = err.split("version is")[1].split("with binary path")[0].trim();
try{
FileWriter writer = new FileWriter("chromeVersion.txt", true) ;
writer.write(chromeVersion) ;
writer.close();
} catch (IOException er ) {}
}
if (!oldVersion){
WebDriverManager.chromedriver().version(chromeVersion).setup();
driver = new ChromeDriver() ;
}
driver.get("https://www.google.com") ;
I got this error when the chrome driver was not closed properly. Eg, if I try to find something and click it and it doesn't exist, the driver throws an exception and the thread ended there ( I did not close the driver ).
So, when I ran the same method again later where I had to reinitialize the driver, the driver didn't initialize and it threw the exception.
My solve was simply to wrap the selenium tasks in a try catch and close the driver properly

Chrome version must be between 71 and 75 error after updating to ChromeDriver 2.46

After update of chromedriver to version 2.46 my tasts fail to initialize.
I got message like this:
Starting ChromeDriver 2.46.628402 (536cd7adbad73a3783fdc2cab92ab2ba7ec361e1) on port 44269

Build info: version: '2.53.1'
It is clearly saying that my browser version is not valid. But I am using Chrome 72.0.3626.119 so it is between 71 and 75.
Selenium version is 2.53.1.
And I am running test through console command with the help of testNG.
Any idea? Every ideas that I found was about changing selenium version but I cant do it.
For me to resolve this problem :
On Windows
cd C:\Users\[myname]\AppData\Roaming\npm\node_modules\protractor
npm i webdriver-manager#latest
webdriver-manager update
webdriver-manager start &
On Cent-OS (I used Cent-OS 7.4.* and it worked fine.)
cd /usr/lib/node_modules/protractor/
sudo npm i webdriver-manager#latest
sudo webdriver-manager update
sudo webdriver-manager start &
I hope this helps you in any way.

...implies that the ChromeDriver v2.46 is not compatible with the Chrome Browser version which is being accessed by your program/webdriver.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You are using chromedriver=2.46
Release Notes of chromedriver=2.46 clearly mentions the following :
Supports Chrome v71-73
Though you mentioned you are using Chrome 72.0.3626.119 possibly there are multiple instances of Chrome Browser installed within your system and your program by default is accessing the Chrome Browser whose version is not between v71.x and v75.x
You are using chrome=67.0
Release Notes of ChromeDriver v2.38 clearly mentions the following :
Supports Chrome v65-67
Solution
Keep JDK upgraded to recent levels JDK 8u201.
Uninstall all the instances of Chrome Browser (you can opt to use Revo Uninstaller).
Upgrade ChromeDriver to current ChromeDriver v2.46 level.
Keep Chrome version between Chrome v71-73 levels. (as per ChromeDriver v2.46 release notes)
For me, I had to update my chrome driver in my project to match the version of Chrome on my local machine.
yarn add chromedriver#76.0.0 -D
https://www.npmjs.com/package/chromedriver
In my case I was getting the same error after my chrome was updated to version 76. Which was happening when chimp tries to use chromedriver to execute the selenium test.

For me it didn't work when I updated the chrome driver by npm (both globally and locally) and then I followed these steps to resolve the issue, which might give some idea on where to check in this kind a issue:
Because exception was thrown in node_modules\chimp\dist\lib\utils\fiberize.js i navigated to that file and found one level above this file node_modules\chimp\dist\lib\chromedriver.js which has the code to start chromedriver.
I added a console.log to chromedriverPath which can be seen below and re-executed the tests to get the chromedriver path in console logs.
Chromedriver.prototype.start = function(callback) {
var self = this;
var port = self.options.port;
if (this.child) {
callback();
return;
}
var chromedriverPath = chromedriver.path;
//this was added my me the see that chrome drive path
console.log("[chimp] " + chromedriverPath);
if (fs.existsSync(chromedriverPath)) {
this.child = processHelper.start(
{
bin: chromedriverPath,
prefix: "chromedriver",
args: ["--port=" + port, "--url-base=wd/hub"],
waitForMessage: /Starting ChromeDriver/,
errorMessage: /Error/
},
callback
);
} else {
callback("[chimp][chromedriver] Chromedriver executable not found.");
}
};
When i got the path of the chromedriver which is used to execute the tests, i just navigated to that folder and replaced chromedriver executable with the most recent version.
I hope this helps.
Try this: Download the compatible ChromeDriver.exe file for the updated version of Chrome browser and replace it. It works for me.

But on running shows the following error:
How can i fixed this error ?
This error message...
org.openqa.selenium.SessionNotCreatedException: session not created
disconnected: unable to send message to renderer
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
I suspect your main issue is the incompatibility between the version of the binaries you are using.
As per the snapshot you have provided the following set of binaries you are using looks fine to me:
JDK: 1.8.0_191
Selenium: 3.14.0
ChromeDriver: 2.43
Chrome: 69.0
Analysis & Solution
As per Unable to receive message from renderer error using chrome driver 2.27 another pottential reason can be presence of antivirus within your localhost which you need to disable.
Ensure that /etc/hosts on your system contains the following entry:
127.0.0.1 localhost.localdomain localhost
#or
127.0.0.1 localhost loopback
Keep Chrome version between Chrome v68-70 levels. (as per ChromeDriver v2.43 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
(WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
(LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint before and after the execution of your Test Suite.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test.

tl;dr
As per ChromeDriver 2.34 doesn't wait until iframe content loads after switching into iframe this issue was also observed with ChromeDriver 2.38 and Chrome 67+ combo and was related to static iframes (part of the originally loaded DOM) which seem to work correctly even till Chrome 66.
Try using JDK 1.8.0_181. I had the same issue after updating to JDK 1.8.0_191.

Timed out receiving message from renderer

Your main issue is the incompatibility between the version of the binaries you are using as follows:
You are using chromedriver=2.38
Release Notes of chromedriver=2.38 clearly mentions the following :
Supports Chrome v65-67
You are using chrome=68.0
Release Notes of ChromeDriver v2.41 clearly mentions the following :
Supports Chrome v67-69
Your Selenium Client version is unknown to us.
Your JDK version is version is unknown to us.
So there is a clear mismatch between the ChromeDriver v2.38 and the Chrome Browser v68.0
Solution
Upgrade JDK to recent levels JDK 8u181.
Upgrade Selenium to current levels Version 3.14.0.
Upgrade ChromeDriver to current ChromeDriver v2.41 level.
Keep Chrome version between Chrome v67-69 levels. (as per ChromeDriver v2.41 release notes)

selenium server, selenium client, on an UBUNTU GUI server

i have a VPS with ubuntu 14.04 LTS and with the desktop package installed, that mean I can launch firefox from a ssh -X session.
To make tests, I launched from my server the selenium standalone server jar (selenium-server-standalone-3.0.0-beta3.jar)
After launching it, in another ssh session, i just enter python commands :
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
And after that, following the instructions from
http://selenium-python.readthedocs.io/getting-started.html#using-selenium-with-remote-webdriver, I enter :
driver = webdriver.Remote(
command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities=DesiredCapabilities.FIREFOX)
After 45sec, i have lots of errors in both server window and client window.
Here is the main error :
Caused by: org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
Error: GDK_BACKEND does not match available displays
I saw some people with the same problem, but even with the latest java and selenium versions, i still got this issue.
Thank you in advance for your help
It seems you're trying selenium 3 with latest firefox version. To support latest firefox with selenium 3, need to download latest geckodriver executable from this link and extract it into you system at any location.
Now to run selenium-server-standalone-3.0.0-beta3.jar use below command :-
java -jar selenium-server-standalone-3.0.0-beta3.jar -Dwebdriver.gecko.driver = "path/to/downloaded geckodriver"
Now you need to set capability with marionette property to true to support latest firefox with selenium 3 as below :-
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
caps["marionette"] = True
driver = webdriver.Remote(command_executor = 'http://127.0.0.1:4444/wd/hub', desired_capabilities = caps)
Note :- For more information about marionette follow this Mozilla official page
