[MM3-users] Re: HyperKitty failure: {"error": "'Thread' instance needs to have a primary key value before this relationship can be used."} (400)

OK, quick test - your guess is correct: Django 4.1.x is the culprit. Downgrading to 4.0.8 brought hyperkitty back to life. Support for 4.1 was introduced with commit 0f50cae8 (Merge branch 'django4.1' into 'master'). As I'm not familiar with mailman's dev-conventions - is there a recommended procedure to report the issue?

If you're willing to help us get our code in shape for Django 4, of course we'd love to have a beta tester.

Sure, no problem, I'm still evaluating mailman and it's not a critical service here, (yet).

best regards, Armin.
