   > As far as I can tell it's to do with the Celery migration to use click for their cli instead of their custom one. I can try and find the stacktrace if you'd like and add it as an issue?
   
   @wolfrubin that would be helpful!
   
   Edit, did quick test:
   ```
   root@5257c48ec87e:/opt/airflow# airflow celery worker
   Traceback (most recent call last):
