@EventHubTrigger cannot deserialize HttpResponseMessage. What is best way to deserialize HttpResponseMessage?

I have a function(@HttpTrigger) which writes HttpResponseMessage to email topic. I am trying to create another function(@EventHubTrigger) to read message from this topic.

````
@FunctionName("EventHubTrigger-EmailCurated")
public void run(
@EventHubTrigger(name = "httpResponseMessage", eventHubName = "email", connection = "AzureEventHubConnection") HttpResponseMessage httpResponseMessage,
final ExecutionContext context) {
logger = context.getLogger();
logger.info("EventHubTrigger-EmailCurated received a httpResponseMessage : " + httpResponseMessage);
}
````
````
Stack: java.lang.RuntimeException: Unable to invoke no-args constructor for interface com.microsoft.azure.functions.HttpResponseMessage. Registering an InstanceCreator with Gson for this type may fix this problem.
Caused by: java.lang.UnsupportedOperationException: Interface can't be instantiated! Interface name: com.microsoft.azure.functions.HttpResponseMessage
````
I understand HttpResponseMessage is an interface. Is there any implementation class available that I can cast to?

Start by examining the @EventHubTrigger parameter binding and the HttpResponseMessage interface mentioned in the report. Reproduce the Gson deserialization failure, then determine whether the supported behavior or documentation should explain how messages written from an @HttpTrigger can be consumed; done requires a clear, tested resolution.
