Steps to reproduce

I encountered the following error while trying to set the 'Maximum age of log entries', but it is not specific to this value. This value may be blank and the error still occurs.

I'm working on Drupal 10.3.1
PHP 8.1

As far as I can tell, the module still works, but these settings cannot be saved through the UI. Saving via drush worked fine.

Proposed resolution

I was not able to work out the issue, but I didn't spend much time on it. Some of the form field configurations are quite complex, so I would guess there is a core bug with validating those fields.

Remaining tasks

Debug and fix

User interface changes

n/a

API changes

n/a

Data model changes

Probably not.
