Drupal InvalidArgumentException Отметка времени должна быть числовой

Question

У меня есть эта ошибка в узле / добавить страницу и страницы деталей узла.

InvalidArgumentException: отметка времени должна быть числовой. dans Drupal\Component\Datetime\DateTimePlus::createFromTimestamp() (стр. 202 из lib\Drupal\Component\Datetime\DateTimePlus.php).

У меня есть drupal 8 версии 8.5.3 PHP 7.1 с включенным модулем Datetime. У меня есть только одна дата поля, я пытался удалить ее, но ошибка все еще существует.

обратный след:
