AWS Lambda + DynamoDB Invalid security token in request

I have a Lambda function that connects with DynamoDB. If I build and deploy this function and run it in my AWS console it works just fine, but if I try to execute it from my IDE (Intellij) it doesn't work. I get the following error message:
The security token included in the request is invalid (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: UnrecognizedClientException;
I tried looking at other questions here and nothing seems to workout. I have two users and each one has one group. One of them has AdministratorAcces and the other has DynamoDBFullAccess and AWSLambda_FullAccess permissions. None of them can execute the function locally. Tried to reconfigure my credentials using aws configure in cmd.
I also tried to create new security credentials. And the problem is not with the function because if I remove the DynamoDB connection code and run and deploy locally the function or deploy it in my AWS console successfuly executes. Anyway I will post below the code of my connection:
AmazonDynamoDB client = AmazonDynamoDBClientBuilder.defaultClient();
DynamoDBMapper mapper = new DynamoDBMapper(client);
MyCustomData data = new MyCustomData("test","12313","test2");
mapper.save(data);
EDIT:
I've been debuging the code where the exact problem occurs and seems that in the class AmazonHttpCLient.java there is a part that checks the credentials. The point is that there are three properties in the AWSCredentials object:
My credentials in the ~/.aws/credentials doesn't have a sessionToken parameter, and I at any moment seted that. Also a friend of mine debuged the same project and said that there is no property sessionToken in his debug. I tried to reinstall AWS CLI, SAM and Intellij, deleted the credentials files and checked if there is no credentials in my variables environment but the problem still persists.

I managed to solve the problem by downgrading my SAM CLI version. It was in 1.15.0 and my friends was in 1.6.2. So I downloaded that specific version and worked like a charm.
I don't know why this happens but I hope this gets fixed in in future versions.
I hope it helps someone having this issue.

Most probably, this error is due to the credentials/aws profile used for establishing connection with AWS account.
To troubleshoot this issue using IntelliJ IDEA, I would suggest you to install AWS Toolkit into your IntelliJ IDEA. Furthermore, use AWS Toolkit to find out which aws profile to use to meet your use-case.
otherwise, refer this existing thread for more other option

How to integrate google api Spreadsheet callback url on my production server

I am reading data from google spreadsheet API using java. I am able to read on my local machine and the URL getting below for auth2:
https://accounts.google.com/o/oauth2/auth?access_type=offline&client_id=679281701678-iacku5po12k0if70abstnthne9ia57kg.apps.googleusercontent.com&redirect_uri=http://localhost:39740/Callback&response_type=code&scope=https://www.googleapis.com/auth/spreadsheets
My callback URL is
http://localhost:62238/Callback?code=4/k6rwrqBFTJ310Yhy9EBpIA7eH9PqL-HXwC3hi9Q0How#
However, when I am deploying my war on the production server so I am not able to see callback function.
If any one knows about this please suggest to me how to integrate on the production server.

Whenever you integrate with any OAUTH enabled google api. You need to provide the restrictions on google dev console like authorized origins and authorized redirect uris. I think you might have provided different port from your local than what is running in your production in your authorized origins, that is why it is not able to connect from your production server but it is able to connect from your local. you can cross check once.

Why is GetServerAuthCodeResult Deprecated? How can I do something equivalent in an Installed Application?

Following this post: http://android-developers.blogspot.com/2016/01/play-games-permissions-are-changing-in.html I have obtained a single use authorization code for use on my backend server as follows:
import com.google.android.gms.games.Games;
//later
Games.GetServerAuthCodeResult result = Games.getGamesServerAuthCode(gameHelper.getApiClient(), server_client_id).await();
if (result.getStatus().isSuccess()) {
String authCode = result.getCode();
// Send code to server...
This seems to works fine, but it presents a question:
1) getGamesServerAuthCode and GetServerAuthCodeResult are marked as deprecated. Why? Should I be using something else instead?
2) How would I do something equivalent in an non-Android installed Java application? I am able to obtain a token on the client application, but I also need to obtain a single use code to pass to my backend server like above. I can't find an equivalent function to get a Server Auth Code. (using com.google.api.client.extensions.java6.auth.oauth2)
I am basically trying to follow this flow: https://developers.google.com/games/services/web/serverlogin but in Java, NOT Javascript. I am attempting to do this in an Android app and a desktop Java app.

1) Yes, in Android use GetServerAuthCodeResult although it is still marked as deprecated. It is the recommended way from Google and it seems they have only forgot to remove the deprecation annotation when releasing to general public.
2) For desktop applications you can follow the instructions here: https://developers.google.com/identity/protocols/OAuth2InstalledApp
Basically from your app you open the system browser (embedded webviews are discouraged) and make a https request to the https://accounts.google.com/o/oauth2/v2/auth endpoint. In the request you supply a local redirect URI parameter i.e. http://127.0.0.1:9004 (you should query your platform for the relevant loopback IP, and start a HTTP listener on a random available port). The authorization code will be sent to your local HTTP listener when the user has given consent or an error such as error=access_denied if the user declined the request. Your application must be listening on this local web server to retrieve the response with the authcode. You also have the option to redirect to a server URI directly claimed by your app, see docs on link above. When your app receives the authorization response, for best usability, it should respond with an HTML page, instructing the user to close the browser tab and return to your app. Also, if you want the Games-scope make sure you are using the https://www.googleapis.com/auth/games as scope in the request, example below, with line breaks and spaces for readability.
https://accounts.google.com/o/oauth2/v2/auth?
scope=https://www.googleapis.com/auth/games&
redirect_uri=http://127.0.0.1:9004&
response_type=code&
client_id=812741506391-h38jh0j4fv0ce1krdkiq0hfvt6n5amrf.apps.googleusercontent.com
Please note that I think you'll have to create and link an app of type other, in the Google Play Developer Console linked-app, for the localhost redirection to work. Use type Web if you plan to redirect to server URI directly, add your server URI to Authorized redirect URIs in the API Manager under section Credentials.

There is finally a proper answer to part 1) of this question!
In the release notes of gms 10.2.0
https://developers.google.com/android/guides/releases#february_2017_-_v102
the new method of obtaining a server code is described. A good example of how to do this is provided here:
https://github.com/playgameservices/clientserverskeleton
I ended up updating Google's baseGameUtils to follow the example above.
Still not sure the proper way to do this for part 2) of the question, at the moment I am sending the token to the server which works but is probably unsafe.

Web Service client - Service definition selected is invalid

i am building a web service on eclipse using Apache AXIS 2 Webservice runtime using Apache Tomcat server (apache-tomcat-7.0.23) while running it on tomcat server it sucessfully shows that the web service is running...
But while creating Webservice client to test the web service and using the wsdl url in the server definition (http://localhost:9090/Axis2WSTest/services/Converter?wsdl), this gives below mentioned error and not letting me to create Webservice client:
The service definition selected is invalid
Can you please suggest me the error and possible solution for it?

The problem could be that your wsdl needs http authentication. I was getting the same error in eclipse, but it was because the server I was connecting to needed authentication and was returning a 401 error, so eclipse was saying it wasn't a wsdl. Eclipse doesn't seem to have the functionality to prompt for authentication, I was able to generate a client in netbeans using the same wsdl url because netbeans knows to ask for authentication.
Generate client from http authenticated wsdl

I was searching for the whole day for an answer for this,generally localhost will be added in your bypass proxy list and hence you will not encounter an error.
Go to windows--> preference-->general--> network-connection and see whether localhost is listed in your proxybypass list.If you are trying to access a external wsdl link and you under
some corporate network having proxy firewall you have to set http proxy/https proxy.

Is this how you are trying to generate client stub ?? If yes, just simply create a java project in eclipse, click on it, then press Ctrl+N, select web service client and enter your wsdl url. (make sure you have made sure you can access the wsdl url, by simply giving it in a browser).

Try replacing localhost with the actual IP address. I was facing the same problem and it worked for me this way

I had exactly same situation. For me the following worked:
I got the lead from rdp's response - "Try replacing localhost with the actual IP address. I was facing the same problem and it worked for me this way"
Using IP didn't work for me. What worked for me:
Instead of - http://servername/SomeWebService/Service.asmx?WSDL
putting FQDN for servername. For example -
http://servername.my.company.com/SomeWebService/Service.asmx?WSDL

I had the same issue and I was able to generate the stubs using soapUI. Please follow the this post. Which contains GENERATING CLIENT JAVA CODE FOR WSDL USING SOAP UI – AXIS2 WSDL2JAVA. Before that please download apache axis2 binary from here and extract it.

Uploading to Youtube via a proxy using the Java Youtube API

So I want to write a servlet which uploads a video to a youtube channel using the Java API, but I can't seem to find a way of specifying that I want to go through a proxy server. I've seen an example on this site where someone managed to do this using C#, but the Classes they used don't seem to exist in the Java API. Has anybody managed to successfully do this?
YouTubeService service = new YouTubeService(clientID, developerKey);

I'm new here so I'm unable to comment on posts (and a little late on this topic), but Jesper, I believe this is the C# sample that the original poster was talking about: How to upload to YouTube using the API via a Proxy Server
I can see no "direct" way of porting that example to Java though, since the GDataRequestFactory doesn't seem to have any proxy-related fields.
I was also having issues with the Java client Library with proxy in our application. Basically, the library picks up the global Java proxy settings:
System.getProperty("http.proxyHost");
System.getProperty("http.proxyPort");
but for some reason not everywhere. To be more precise, even with a proxy server properly configured in Java, YouTube authentication (calling service.setUserCredentials("login", "pwd")) would use a direct connection and ignore the proxy. But a video upload (calling service.insert(...)) would use the proxy correctly.
With the help of folks at the official YouTube API mailing list, I was able to nail this down. The issue is that the authentication is performed using SSL (HTTPS) and since there is a different set of properties for the HTTPS proxy, this didn't work. The fix is to simply set https.proxy* properties as well (in addition to http.proxy*), so that these point to a valid proxy server too:
System.getProperty("https.proxyHost");
System.getProperty("https.proxyPort");
