@Marusyk - do let us know if you have more follow up questions. If not, I’ll proceed to close this issue.

ah, my apologies. my recommendation was incorrect, the async method should include session as one of the parameters.

The specific error means that the application is trying to receive messages on a session which has no more messages on it. When such an error is seen, the session can be abandoned and the program should accept the next session.
