Non-existent service "entity.manager" for Drupal 9

After updating a test site to Drupal 9, the following error would happen when either trying to access a View that was already using the Name Depth, or trying to add it:

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "entity.manager". in Drupal\Component\DependencyInjection\Container->get()

To resolve for Drupal 9, will need to update 'entity.manager' to be 'entity_type.manager'.
