Drupal 11 compatibility fixes

First, we need to resolve #3537760

alorenc → closed merge request !5

Hi,

I faced the same issue while installing this module on Drupal 11.2.2.
After applied Merge Request #7, I was able to install the module successfully, and it is now compatible with Drupal 11.2.2.

The changes are correct, marking it as RTBC.
