Dummy update_handler in the PodsRESTHandlers.php resolve problem

/**
* Dummy update handler for WordPress REST API compatibility
*
* @param mixed $value Value to update
* @param object $object The object being updated
* @param string $field_name Field name
* @return bool
*/
public static function update_handler( $value, $object, $field_name ) {
// Пустой метод – реальное сохранение идет через save_handler hook
return true;
