I have a field definition set up like below. I want Drupal to do all the heavy lifting for me, so my definitions are minimal and rely on Drupal defaults:
$fields[$field] = BaseFieldDefinition::create('entity_reference') ->setSettings([ 'target_type' => 'target_entity', 'handler' => 'default', 'handler_settings' => [ 'auto_create' => true, ], ]) ->setDisplayOptions('form', array( 'weight' => $weight, )); ; target_entity is just a simple bundleless entity.
This creates an entity reference auto-complete field in forms, but if I type something that doesn’t match any existing entities, Drupal will say that no matching entities found and will refuse to create a new one.
How do I make the auto_create setting work?
