I am new to drupal and not a coding expert. I get this error: Only variables should be passed by reference in include() for the lines $tmp->role = count($parent->getRoles()) ? end($parent->getRoles()) : ”;

public function getRelations($isAll = false){     $user = DrupaluserEntityUser::load(Drupal::currentUser()->id());     if ($isAll) {         /** @var UserService $userService */         $userService = Drupal::service('avofamilles.user_services');         $relations = $userService->getAllRelations($user->id());     } else {         $relations = $user->get('field_relations')->getValue();     }     $data_relations = [];     if ($relations) {         foreach ($relations as $relation){             /** @var User $parent */             $parent = DrupaluserEntityUser::load($relation['target_id']);             if (!$parent) {                 continue;             }             $civility_relation = $parent->get('field_civility')->value;             $civility = "";             if ($civility_relation == "father") {                 $civility = "Ex-Compagnon";             } else if ($civility_relation == "mother") {                 $civility = "Ex-Compagne";             } else {                 $civility = "Avocat";             }             $image_relation = $parent->get('user_picture')->getValue();             $avatar_relation = '';             if (isset($image_relation[0]['target_id'])) {                 $file = File::load($image_relation[0]['target_id']);                 $avatar_relation = file_create_url($file->getFileUri());             }             $tmp = new stdClass();             $tmp->uid = $relation['target_id'];             $tmp->name = $parent->field_firstname->value;             $tmp->email = $parent->getEmail();             $tmp->civility = $civility;             $tmp->couleur = $parent->get('field_couleur')->value;             $tmp->avatar = $avatar_relation;             $tmp->avatar_url = $parent->get("field_avatar")->value;             $tmp->is_waiting = $parent->get("field_is_waiting")->value;                       $tmp->role = count($parent->getRoles()) ? end($parent->getRoles()) : '';             $tmp->roles = $parent->getRoles()[1] ? : null;              $data_relations[] = $tmp;         }     }     return $data_relations; }
