The above exception was the direct cause of the following exception:

Notes

I found this error when there was a typo in the test name: nautobot.utilities.tests.test_filters.NaturalKeyOrPKMultipleChoiceFilterTest.test_filter_multiple_name_excludetes.
The correct test is test_filter_multiple_name_excludetes. The tes on the end caused this entirely unrelated error and I ended up spending close to an hour debugging Docker, back-tracking through my commits, setting up a new clean repo, etc. before noticing the typo in the test name. :(
