Azure java function : No HTTP triggers found when deploying

Question

I just wrote a new function with java runtime 17. Locally, I am able to run the azure function but the deployment is giving "No HTTP triggers found.". This started happening today. It was working till yesterday. Not sure what has changed for java on jan 31st 2024.

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}

Deployment:

public class HttpTriggerJava1 {
@FunctionName("HttpTriggerJava1")
public HttpResponseMessage run(
        @HttpTrigger(name = "req", methods = {HttpMethod.GET, 
HttpMethod.POST}, authLevel = AuthorizationLevel.FUNCTION) 
  HttpRequestMessage<Optional<String>> request,
        final ExecutionContext context) {
    context.getLogger().info("Java HTTP trigger processed a 
    request.");
    String query = request.getQueryParameters().get("name");
    String name = request.getBody().orElse(query);
    if (name == null) {
        return 
request.createResponseBuilder(HttpStatus.BAD_REQUEST).body("Please 
pass a name on the query string or in the request body").build();
    } else {
        return 
request.createResponseBuilder(HttpStatus.OK).body("Hello, " + 
name).build();
      }
   }
}

I was facing the same issue while deploying Java Http Triggered Azure function using Visual Studio code.

To resolve this, I have downgraded Azure Functions Extension version to 1.13.1 in Visual Studio Code=>Extensions=> Search for Azure Functions=>click on drop down of Uninstall->select Install other version=>select 1.13.1 version.
