With the changes in #3527916 I am now seeing the following error on the Google Tag configuration form, I don't know if it exists elsewhere yet or if this is an isolated case.
Warning: Undefined array key 1 in Drupal\trash\EventSubscriber\TrashIgnoreSubscriber->onRequest() (line 69 of /app/web/modules/contrib/trash/src/EventSubscriber/TrashIgnoreSubscriber.php). =>
In this case, for https://git.drupalcode.org/project/trash/-/commit/e07d5a4ef3851a9175265f... the $entity_form is simply "google_tag_container", which is breaking the explode().
I am also seeing this on a fresh install of simplytest.me with trash and google_tag installed.
