Prometheus 'expected label name, got "BCLOSE"' error

I have an application running on port 7070 on my local. It exposes and endpoint /metrics and shows all the tags that are available. Prometheus is not able to get these data and it says 'expected label name, got "BCLOSE"'.
I have been trying to figure this out but not sure why this code doesn't work:
import io.micrometer.prometheus.PrometheusMeterRegistry;
import io.prometheus.client.exporter.common.TextFormat;
import metrics.PrometheusRegistry;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.HttpHeaders;
import javax.ws.rs.core.Response;
import java.io.IOException;
import java.io.StringWriter;
import java.io.Writer;
#Path("/metrics")
public class MetricsController {
private final PrometheusMeterRegistry prometheusRegistry = PrometheusRegistry.INSTANCE();
#GET
public Response getMetrics(#Context HttpHeaders headers) {
Writer writer = new StringWriter();
try {
TextFormat.write004(writer, prometheusRegistry.getPrometheusRegistry().metricFamilySamples());
} catch (IOException e) {
e.printStackTrace();
}
return writer.toString();
}
}
Also, the application is neither a sprintboot nor a spring project.
Tried this:
#GET
public Response getMetrics(#Context HttpHeaders headers) {
String accept = headers.getRequestHeader("Accept").get(0);
System.out.println("Accept Header --------------------------> " + accept);
return Response.ok(prometheusRegistry.scrape(), "application/openmetrics-text").build();
}
Even then the same error as above SS.

This worked for me:
#GET
public Response getMetrics() {
return Response.ok(prometheusRegistry.scrape(), TextFormat.CONTENT_TYPE_004).build();
}

Braintree webhooks: Error: payload contains illegal characters

I am trying to consume Braintree webhooks in a java microservice (Micronaut fwiw).
The issue that I'm having is that when I try to parse the webhook body, I get an error: " Error: payload contains illegal characters", which it does. So I'm wondering if maybe I'm casting the request body to something thats inserting the characters...? (the body is x-www-form-urlencoded)
package com.autonomy;

public HttpResponse<?> consumeWebhook(#Body String body) {
BraintreeGateway gateway =
new BraintreeGateway(determineEnv(env),

);
logger.info(body);
try {
String decodedBody = body; // was doing a decode here that didn't do anything
logger.info(decodedBody);
Map<String, String> map = new HashMap<>();
Arrays.stream(decodedBody.split("&")).toList().forEach(pair -> {
String[] param = pair.split("=");
map.put(param[0], param[1]);
});
WebhookNotification webhookNotification = gateway.webhookNotification().parse(
map.get("bt_signature"),
map.get("bt_payload")
);
..... Do stuff
} catch (Exception e) {
logger.error(String.format("Braintree webhook failed for %s. Error: %s", kind, e.getMessage()), e);
return HttpResponse.status(HttpStatus.BAD_REQUEST);
}
return HttpResponse.status(HttpStatus.OK);
}
private Environment determineEnv(String env) {
if (env.equals("beta") || env.equals("prod")) {
return Environment.PRODUCTION;
} else {
return Environment.SANDBOX;
}
}
}

Try:
#Post(consumes = MediaType.APPLICATION_FORM_URLENCODED)
public HttpResponse<?> consumeWebhook(String bt_signature, String bt_payload)
BTW: What 'illegal characters' were in the body that was logged?

Unable to run JUnit5 PACT test. No method annotated with #Pact was found on test class ConsumerContractTest for provider ''

I'm trying to get a PACT test running on JUnit5. We use JUnit4 for others, but this one will be JUnit5. The error occurs when running the JUnit5 test using the pact annotation on the RequestResponsePact method.
Error : No method annotated with #Pact was found on test class ConsumerContractTest for provider ''.
I've seen Basic Pact/Junit5 Test Setup fails. No method annotated with #Pact was found for provider error, but this is issue was due to the #PactTestFor(pactMethod = "examplePact") not matching the #Pact method name. But on my code it does match.
I can't seem to figure out why I get the error and especially why the error has an empty provider(provider '') despite defining one("some-provider").
Example code :
import au.com.dius.pact.consumer.MockServer
import au.com.dius.pact.consumer.Pact
import au.com.dius.pact.consumer.dsl.PactDslJsonArray
import au.com.dius.pact.consumer.dsl.PactDslWithProvider
import au.com.dius.pact.consumer.junit5.PactConsumerTestExt
import au.com.dius.pact.consumer.junit5.PactTestFor
import au.com.dius.pact.model.RequestResponsePact
import groovyx.net.http.RESTClient
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.ExtendWith
import org.springframework.http.HttpStatus
#ExtendWith(PactConsumerTestExt.class)
class ConsumerContractTest {
#Pact(consumer = "some-consumer", provider = "some-provider")
RequestResponsePact examplePact(PactDslWithProvider builder) {
builder
.given("provider state")
.uponReceiving("Contract description")
.method("GET")
.matchPath("/endpoint")
.willRespondWith()
.status(200)
.headers(["Content-Type": "application/vnd.pnf.v1+json"])
.body(new PactDslJsonArray())
.toPact()
}
#Test
#PactTestFor(pactMethod = "examplePact")
void exampleTest(MockServer mockServer) {
def client = new RESTClient(mockServer.getUrl())
}
}

Not sure if that's just the gist you've posted here but I see the return word missing and also the #PactTestFor annotation missing the provider and version. Here is an example I have that works for my project.

Accessing request payload in V2 DialogFlow fulfillment webhook

I'm trying to parse the request sent to a java based fulfillment in V2 of the API. I can't find any example documentation in Java for doing this in V2 of the API (com.google.cloud:google-cloud-dialogflow:0.38.0-alpha dependency in my project).
So far I've got as far as writing a very basic Spring MVC controller to accept the request.
How can I parse out the payload in the request, e.g. the parameters that dialog flow sent ?
import com.google.cloud.dialogflow.v2beta1.WebhookRequest;
import com.google.cloud.dialogflow.v2beta1.WebhookResponse;
import com.google.protobuf.Descriptors;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.util.Map;
import java.util.stream.Collectors;
#RestController
#RequestMapping("test")
public class TestRequestRestController {
private static final Logger log = LoggerFactory.getLogger(TestRequestRestController.class);
#PostMapping("test1t")
public WebhookResponse getTest1(WebhookRequest request) {
System.out.println(request.toString());
return WebhookResponse.newBuilder().setFulfillmentText("Example reply 1 ").build();
}
}

Not sure about WebhookRequest and WebhookResponse.
The code below code might help you.
import org.springframework.http.HttpEntity;
#PostMapping("test1t")
public String getTest1(HttpEntity<String> httpEntity) {
String reqObject = httpEntity.getBody();
System.out.println("request json object = "+reqObject);
//Get the action
JSONObject obj = new JSONObject(reqObject);
String action = obj.getJSONObject("result").getString("action");
//Get the parameters
JSONObject params = obj.getJSONObject("result").getJSONObject("parameters");
String response = "Hello from Java.";
return "{'speech': '"+response+"', 'displayText':'"+response+"'}";
}

How to set response header for digital asset in AEM CQ6.1?

I have a request that if a user directly accesses a .pdf asset(for example, http://localhost:4505/content/dam/company/us/en/962059.pdf) from AEM CQ 6.1, I need to send a custom http respone header. This is what I wrote. This is only works if I open a .html page. But it doesn't work if I open a .pdf in browser. So what did I do wrong?
Thanks

Just a update, initialy I thought the problem only happens to .pdf file, but this also happens to image file. So I created a regular JSP web application, and this code is working for regular web app. Is there something funny on AEM side?
