ServiceBusQueueTrigger IMessageReceiver Binding for Java throws error

[M-Mendonca]

I am using an ServiceBusQueeue Triggered azure function in Java. I have disabled the "autoComplete" message because i want to receive the message and manually complete it. I am trying to make use of "IMessageReceiver" to manually complete the message after it is received and processed.

Im getting below error :

Is there anything wrong that I am doing ?

Below is my host.json file:

{
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[2.*, 3.0.0)"
  },

  "extensions": {
    "serviceBus": {
      "messageHandlerOptions": {
        "autoComplete": false,
        "maxConcurrentCalls": 1
      }
    }
  }
}

public class TestFunction {
   @FunctionName("Test-Function")
    public void run(
            @ServiceBusQueueTrigger(name = "Message", queueName = "test_queue",
                    connection = "TestServiceBusConnection")  String Message , @BindingName("IMessageReceiver") IMessageReceiver messageReceiver,
            final ExecutionContext context
    )  {

        context.getLogger().info("Received message: " + Message);
     
    }
}

Hi @M-Mendonca , can you share how you IMessageReceiver class is defined and any document you use to create it? The binding name should be @BindingName("MessageReceiver"), please let me know which document you are referring so I can help to update it with correct binding name. Thanks.
