@pingevt I have just one more warning but get errors when I try to fix it, maybe we can look at it together:

\Drupal calls should be avoided in classes, use dependency injection instead
(DrupalPractice.Objects.GlobalDrupal.GlobalDrupal)

Here's the line:
$msg = \Drupal::translation()->formatPlural($result_count, '1 result loaded.', '@count results loaded.');

I tried the following use statement:
Drupal\Core\StringTranslation\TranslationManager

But haven't figured out how to use the function correctly in the code itself!
