To Reproduce

tox -e py38-dj42

Expected behavior

Should not have DeprecationWarnings

Version

• [ ] I have tested with the latest published release and it's still a problem.
• [x] I have tested with the master branch and it's still a problem.

Additional context

Will need to identify the specific Deprecation and refactor as needed.
