Service remoting in Java with Reliable Services Fails

Question

I have created a simple Stateless Reliable Service on a Service Fabric cluster set up on Azure. I have tried to access the service using Service Remoting as guided [here] (https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-services-communication-remoting-java). I have created the following Java files to implement the codes suggested in the guide:

1. TestRemoteAccess: implements the following methods - helloWorldAsync() and createServiceInstanceListeners()
2. TestRemoteAccessInterface: interface of the service that includes - CompletableFuture helloWorldAsync();
3. TestClient: calls the remote service method using the following code -
   MyService helloWorldClient = ServiceProxyBase.create(MyService.class, new URI("fabric:/MyApplication/MyHelloWorldService"));
   CompletableFuture message = helloWorldClient.helloWorldAsync();
   System.out.println(" TEST -- " + message);

When I try to run the TestClient as a Java application from one of the nodes inside the service fabric cluster I get the following error message:
system.fabric.exception.FabricException:
TEST -- java.util.concurrent.CompletableFuture@7cd62f43[Completed exceptionally]

Can anyone please suggest what could be the reason for such error even when I am trying to access the service from within the service fabric cluster? I have been stuck with such a simple service access for days and so, I will appreciate any sort of help with regard to accessing a stateless service from within the service fabric cluster using a TestClient Java app.

Many thanks.
