URL: https://github.com/apache/airflow/issues/11301#issuecomment-705173571
> 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:
```
