Answer: You are encountering a new bug with celery, reported here: https://github.com/celery/celery/issues/7409 The workaround you can try is to pin the versions of your dependency for celery to an older version (i.e. before release of the celery bug). For instance, my requirements.txt includes: celery==5.2.3  or on the command line you might just be able to run pip install celery==5.2.3  (For reference, the versions where I was seeing the error reported here were celery 5.2.5 & click 8.1.2) Hopefully this gets fixed upstream and we can remove our version pins.
