Unique field constraint does not work with any field main property name that is not "value"

function hook_entity_bundle_field_info_alter(&$fields, EntityTypeInterface $entity_type, $bundle) { if (!empty($fields['field_some_reference'])) { $fields['field_some_reference']->addConstraint('UniqueField', [ 'message' => 'An entity reference %value already exists.' ]); } }

$value_taken = (bool) \Drupal::entityQuery($entity_type_id) // The id could be NULL, so we cast it to 0 in that case. ->condition($id_key, (int) $items->getEntity()->id(), '<>') ->condition($field_name, $item->value) ->range(0, 1) ->count() ->execute();

Hiding patch #45 as it's incomplete and omitting a lot of work on tests. The rebase should have happend on the feature branch as well I think in this case.

Adding it to the list here: #3339883: Employees of Dotsquares are posting mass re-roll patches which are invalid and/or incomplete →

Although some work on tests was done here, it doesn't look like any scenarios were covered that weren't also covered in 📌 UniqueFieldValueValidator works only with single value fields Fixed which resolves the original issue.
