Lookup table

Hi, is this on a locally hosted version of CommCare?

You need to have 'celery' running in order to perform this action. Celery is the background task processor.

You can check it's status as follows:

commcare-cloud <env> service celery status

OR more directly if you are logged into the machine where you expect it to be running:

sudo supervisorctl status

I was using commcarehq. Thank You the issue was resolved.
