Deprecation Error Solutions

• drupal_set_message

  • \Drupal::service('messenger')->addMessage(....) is a replacement for drupal_set_message in .module files, but in classes, the messenger service should be injected.
  • For any form class that inherits FormBase (or any other class that inherits MessengerTrait), replace drupal_set_message with $this->messenger->addMessage
  • Use method addError for drupal_set_message(..., ‘error’), addWarning for drupal_set_message(..., ‘warning’), etc. See the API docs

  *From https://www.drupal.org/node/3033656
