This is the error occurred in the last few hours

I found that is_ai_beta is gone in the new API. So I move this to the optional arguments.

My apologies, I wasn't completely quite right about my last response:

After checking for responses from API endpoints related to users (/users, /auth/token, /users/me) I found out that such json responses don't have attributes show_popup_version, credits, credits_subs, is_ai_beta anymore.

Attribute is_ai_beta gone from all responses completely, but show_popup_version, credits, credits_subs still present in ExtendedUser model (used for logged-in users). Also, response for logged-in users got new field has_mail, which should have been added to ExtendedUser model. And tag and ai post models also got new fields.

So I make changes in library and push new commit, which fixes the problem.
