Null error in .module

I am on the phone. The code looks good. If you create a MR I can include the change in the repo.

If not I will apply it during the weekend.

Hm, it looks like there was already an issue for that here - https://www.drupal.org/project/simple_entity_merge/issues/3419893 🐛 php 8.1 - explode(): Passing null to parameter #2 ($string) of type string is deprecated Fixed

We can close it then. Can you try to use the latest Dev version?
