Error acknowledging a queue: Queue.ack(): Unidentified ack #44

Closed jhon-andrew closed 3 years ago

jhon-andrew commented 3 years ago

When acknowledging a queue, I am getting this error:

Queue.ack(): Unidentified ack : 735fae706d31ca7e0488377735c75e4d

What is causing this error and how can I avoid it?

Is it possible that you already ack the same message twice ?

After the error, you can check the queue collection and check if either this ack ID is missing from the table, or delete is non null.

Thank you for your response. I don't think that's the case because the first task I get is the one that returns that error.

But I have seem to manage and fix the issue already. It looks like the task performed after getting a queue took very long and it was already put back to queue before I acknowledge it is done.

Extending the visibility fixed the issue.

Thanks!
