Since Drupal 8, the community is actively updating the source code. Deprecations are something to deal with. This blog post shows you how to monitor your code.

There is a simple way for checking. The drupal-check package will inspect your code:

composer require mglaman/drupal-check --dev

 Now run

 drupal-check -a web/modules/custom

The result was the following:

 ------ ----------------------------------------------------------------------
  Line   alter_entity_autocomplete/src/EntityAutocompleteMatcher.php
 ------ ----------------------------------------------------------------------
  28     Cannot call method getReferenceableEntities() on object|false.
  35     Call to an undefined static method Drupal::entityManager().
  36     Call to an undefined static method Drupal::entityManager().
 ------ ----------------------------------------------------------------------

Now look up de the deprecation, fix it and run again! :)
