Publishing a message succeeds but causes an error: "failed to notify : id="

[julianbraha]

My publisher is successfully publishing messages, and my subscriber is receiving them. But every time a messaged is published, the publisher has an error: "failed to notify : id=". What causes this error?

Please show me your code.

I've found the problem. After publishing the message, I was not using awaiter.get().await; like in the publishing example. Adding this solved the problem.
