Error on node delete

Fixed with

if (!empty($bee_settings['bookable_type']) && $node->hasField('field_availability_' . $bee_settings['bookable_type'])) {
    if ($bat_unit = $node->get('field_availability_' . $bee_settings['bookable_type'])->entity) {
      bat_unit_delete($bat_unit);
    }
   ...
  }
