Answer 1

Hi @LeelaRajeshSayana-MSFT - Thanks for your response. The issue i am facing is in my local. It is a simple function...below is the code snippet

@FunctionName("healthCheck")
public HttpResponseMessage healthCheck(@HttpTrigger(name = "req", methods = {
       HttpMethod.GET }, authLevel = AuthorizationLevel.ANONYMOUS) HttpRequestMessage<Optional<String>> request,
       final ExecutionContext context) {
    System.out.println("The PAN Service is up and running");


return request.createResponseBuilder(HttpStatus.OK).body("The PAN Service is up and running").build();

Hi @Umamaheswara R Avula Thank you for sharing your code snippet. The function app signature seems correct. Can you put a break point at the function definition and see if it is getting hit when launched in debug mode?

Would you also give a try by using the code sample provided in the GitHub repo outlined in the documentation Example "Hello, world" Spring Boot application that runs on Azure Functions and see if that helps.
