==============================================================================

 #1298273089: regularExpression "^[2356]$" in RegularExpressionValidator contained an error.
 `TYPO3\CMS\Extbase\Validation\Exception\InvalidValidationOptionsException` thrown in file
 :file:`typo3/sysext/extbase/Classes/Validation/Validator/RegularExpressionValidator.php` in line 50.

This happens when no regular expression delimiter is used.

Correct usage:

::

   /**
    * @validate RegularExpression(regularExpression="/^[2356]$/")
    */
   public $someOption;
