Getting "Unknown error" for CeleryHealthCheck

[GyanP]

I digging this error and found the actual error "No result backend is configured" in
https://github.com/KristianOellegaard/django-health-check/blob/master/health_check/contrib/celery/backends.py at line 20

result.get(timeout=timeout)

Can anyone help me on this?

Thanks

Hi @GyanP

thanks for reaching out. I presume it's most likely because you don't have a result backend configured for celery. Check our there setup guide to see how its done.
If you have it setup, there is a trouble shooting guide for that:
http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html#result-backend-doesn-t-work-or-tasks-are-always-in-pending-state

In any case, the message is valid and cause for action :)

Cheers

Hi @codingjoe , @KristianOellegaard ,

We are facing the same issue on manage.py health_check management command.
We use Redis as a broker and result backend.

Need to mention, that we have next version:

• celery[redis]==5.1.2

When we are running from shell same task which used in that command, we are getting result as expected. And also we checked that backend configured correctly:

from health_check.contrib.celery.tasks import add
add_result = add.apply_async(args=[4,4], expires=3)
print(add_result.backend)

And the response is: <celery.backends.redis.RedisBackend at 0x7f8a9ae043a0>.

But when we are running management command, we see that result backend is <celery.backends.base.DisabledBackend object at 0x7f8695ff0310>
