Thanks for incorporating my changes @sakshamgupta05 and thanks for the
review @aromanenko-dev :)
> Just wondering - is it possible to have a regression test for that?
Not sure what kind of environment is available for (automated?) regression
tests, but in order to reproduce this bug you'd need a RabbitMQ instance and
some dummy publisher I guess. And yet, this is some kind of race condition, so
not sure how reproducible it would be after all.
