I have a referenced entity named - field_cp_level2_ref_level3. This field belongs to level3 content type. when I dump the $entity, I see the field as below:

entity:node:level3::field_cp_level2_ref_level3 => Drupal\Core\Field\EntityReferenceFieldItemList (9) Depth Limit

how to read the value of this field? I tried to read the value as below:

$var =  $entity->$node->field_cp_level2_ref_level3->value;

dpm($var) returns null. how to read this field?

You can use $entity->field_x->referencedEntities(); which will return an array of referenced entity objects

  • doing so, throws the below error - "Error: Call to a member function referencedEntities() on null "

  • That suggests there's nothing in your field. Maybe wrap it in an is null check.
