Run missing entity Schema updates

⚠️ WARNING: Potential data loss. Use with caution.

scp_base.module
/**
 * Run missing database schema updates.
 */
function mymodule_update_10001(&$sandbox) {
  $entity_type_manager = \Drupal::entityTypeManager();
  $entity_type_manager->clearCachedDefinitions();
  $change_summary = \Drupal::service('entity.definition_update_manager')->getChangeSummary();
  foreach ($change_summary as $entity_type_id => $change_list) {
    $entity_type = $entity_type_manager->getDefinition($entity_type_id);
    \Drupal::entityDefinitionUpdateManager()->installEntityType($entity_type);
  }
}

Issue:

When you see the "Entity type needs to be updated" message on the Drupal status page, usually it's not possible to solve it without custom code.

Solution:

Use this update hook in your custom module to force entity definition updates on next deployment.

Conclusion:

This is basically "drush entup", which was removed because it lead to data deletion in certain instances.

Beware:

Only use with caution and verify if this really yields the result you wanted - especially test for potential data loss.

Docs for the service if you want to know more can be found on drupal.org.
