Not allowed error in legacy sections with PHP 8.1 and 8.2

[ywarnier]

Something is broken in the master branch when using PHP 8.1 or 8.2. When going to the administration section, we get an api_not_allowed() right after logging in.

The logs complain about something to do with USerBundle (and Sonata), but it seems to only be as NOTICE.

I'm not having the issue anymore. Not sure what has changed.
