TypeError : implode(): Argument #1 ($pieces) must be of type array, string given dans implode() (*/web/modules/contrib/pathauto/src/Form/PathautoSettingsForm.php ligne 255)

Unable to replicate on a fresh Drupal 10.1.0 website with PHP 8.1.18.

Currently, this issue has no patches or MRs so I'm changing to status to "active".

That value is set by an update, did you run updates?

If you run this in the database, what does it say?

select * from config where name='pathauto.settings';

Hi @tyler36,

Having the same problem, adding patch.

The patch in #5 works. I set the 'safe_tokens' to NULL and there wasn't a warning.

However, before applying the patch, I cleared the 'Safe tokens' textarea on admin/config/search/path/settings. That didn't result in a warning because 'safe_tokens' was an array in the db. In the OP's db 'safe_tokens' is either NULL or missing and it might be good to figure out why.

patch #5 working, thanks
