  // Attach our custom process callback to each entity reference element.

      // Add our #validate callback to the entity form.
      // This prevents the exception on entityconnect elements caused by
      // submitting the form without using the entityconnect buttons.
      $form['#validate'] = !isset($form['#validate']) ? [] : $form['#validate'];
      array_unshift($form['#validate'], [
