Basic.publish: (406) PRECONDITION_FAILED - message size larger than configured max

[Muskanb]

I've encountered this error while passing arguments that are purely strings, and I'm doubtful that they can generate a size this large:
exception: Basic.publish: (406) PRECONDITION_FAILED - message size 179010654 is larger than configured max size 134217728

This is my defined task throwing this error :
@shared_task
def test(
arg1, arg2,arg3,
arg4=None, arg5='github', arg6="full", pullRequestId=None, baseBranchName='', checkRunId=None
):
These are either strings or integers

@auvipy It would be great if you could help :)

Had the same problem a year ago or so. The error only appeared if a pod had been running for a little bit of time. Tracked the bug down to the way Sentry patched into Celery, which appended a trace ID to the headers of the traces. At some point, we were sending tiny messages with 15Mb inane headers.
If you can reproduce it, see if you can get a hold of the actual payload to rabbitmq :)
