And?

To expand a bit on Claude's technically correct answer -- this warning is likely caused by your code or a third-party library you're using. Running under python -Werror will tell you where this warning originates.

I'm not any closer to understanding which third party package is throwing this error:

$ python -Werror manage.py runserver

It's not a Django issue, please see https://github.com/pypa/virtualenv/issues/555.

Thanks for the fix! Sorry I wasn't any clearer when opening the ticket, but the stacklevel fix makes lots of sense and can hopefully assist in debugging in future scenarios.
