I have got quite the same problem here when calling function sdk.create_group with Python sdk (but it works for other functions). In fact it creates the group as expected but still triggers this weird error
I have also looker-sdk version 24.4.0 and my looker instance is on 24.4.28 (Looker original)

I've fixed this issue, but I can't create a new branch in this repo. Can somebody please help me fix the permission issue and assist me in making my first contribution? Thank you.
