Celery Daemon receives unregistered tasks
Solution 1:
Late answer, but maybe it helps someone.
Have you seen http://docs.celeryproject.org/en/latest/userguide/tasks.html#automatic-naming-and-relative-imports ?
You should start the worker with --loglevel=info, that way it will log a list
of registered tasks when it starts up. You must make sure the names the tasks are registered
with matches the name you are sending in messages.
