I have a Drupal 8 module which hasn't been updated for 5 years. I m trying to update to current version of Drupal.

The error I get is

Error: Call to undefined method Drupal::entityManager()

The code causing the error is below.

      $viewbuilder = \Drupal::entityManager()->getViewBuilder('paragraph');
      $data = $viewbuilder->view($paragraph);
      $array['#cache']['tags'][] = 'node:' . $node->id();

When I search one suggestions is to load through drupal service like below


This gives a similar error, as does using EntityTypeManager


How do I update this code?

Thanks for any help

  • Welcome to Drupal Answers! From the question, I understand that every time you call a \Drupal method, you get an error saying that method does not exist. Is that correct? Otherwise, what you do you mean with a similar error?

View builders are now retrieved from the service entity_type.manager, which can be retrieved globally using \Drupal::entityTypeManager():




In Drupal 10, the code to get an entity view builder is used, for example, in BlockViewBuilderTest::testBasicRendering().

$builder = \Drupal::entityTypeManager()->getViewBuilder('block');
$output = $builder->view($entity, 'block');

The same code is used in Drupal 9 and Drupal 8.9.

Older code used Drupal::entityManager(), but as the documentation page says, that method has been deprecated and removed in Drupal 9. \Drupal::entityTypeManager() should be instead used in most cases.

If you get an error about \Drupal::entityTypeManager() being a non existing method, then the core/lib/Drupal.php file is probably corrupted.

The entity_field.manager is a completely different service and it is not the service you need to use. The class implementing it (EntityFieldManager) does not define any getViewBuilder() method.
