Having difficulty examining Celery with SQS Backend

I have been utilizing Celery for my asynchronous task processing, along with SQS on Amazon as my messaging server. All of a sudden, the tasks have ceased processing and upon inspecting the Celery queue using the following code:

from celery.task.control import inspect
i = inspect()
i.scheduled()

An error was returned:

SQSError: SQSError: 400 Bad Request
<?xml version="1.0"?><ErrorResponse xmlns="http://queue.amazonaws.com/doc/2012-11-05/"><Error><Type>Sender</Type><Code>InvalidParameterValue</Code><Message>Can only include alphanumeric characters, hyphens, or underscores. 1 to 80 in length</Message><Detail/></Error><RequestId>adbc0bc9-d1e2-5ab7-bd59-5a7a20cb876c</RequestId></ErrorResponse>

This implies that an invalid parameter is being passed, but since Celery is responsible for generating the SQS request, identifying the issue can be challenging. How can this be resolved?

Answer №1

As stated on this github thread:

The current limitation is that you are unable to check the status of any worker within the cluster.

This restriction is due to the fact that (as mentioned in the documentation):

SQS does not yet support commands for controlling workers remotely.

Therefore, at this time, it appears impossible - your best option (and how I resolved the issue that brought me here) might be to directly interact with the queue using boto3.
