I'm afraid, I did something wrong. But I don't understand what. I could use some help.

There is a message "Pyhon package / build (3.8) (pull request)" failing. Which reads Imports are incorrectly sorted and/or formatted. In my commit I just replaced / with os.path.sep. See https://github.com/plone/bobtemplates.plone/pull/532/files. I did not change any imports.

In Plone we use isort with a rule in setup.cfg. So running isort should fix it.
