You should first make sure that it is correct to acknowledge the
message. If there were any asynchronous events that could fail and that
were triggered as a result of the message then you might as well use
automatic acknowledgements.

I'm not sure why the event sender is null in your example. That may well
be a bug in EventingBasicConsumer, which is classed as experimental.
Using the sender would be the preferable approach. I will file a bug to
investigate why the value is null. Thanks for reporting this.
