Call to a member function id() on null

A block could be missing, but also the references in the block can also be missing.

/** @var \Drupal\Core\Entity\EntityInterface $reference */
/** @var \Drupal\Core\Entity\EntityInterface $reference_clone */
$reference = \Drupal::service('entity_type.manager')->getStorage($target_type)->load($value['target_id']);\
$reference_clone = $reference->createDuplicate();

These two lines need a null check.

@skyredwang I added basics null check, but I don't understand your entire idea please can you give me details about it?

Good morning,
Reviewing #6 i think that using the PHPUnit framework and its isNull method is not the best solution.
I am attaching a new patch that checks if the reference is an instance of ContentEntityInterface.
