PHP Warning: Undefined variable $dbResId

  • After updating PHP to version 8.1 I’m getting following warnings in debug.log:

    PHP Warning: Undefined variable $dbResId in /[…]/wp-content/plugins/ultimate-maps-by-supsystic/modules/marker/models/marker.php on line 143

    I think the if ($dbResId) check should be replaced with either if(isset($dbResId) && $dbResId) or just if(isset($dbResId)).
