 * Hi @robyebf,
 * Thanks for reporting this!
 * The `Undefined array key 3` warning in `class.ui.screen.base.php` is a PHP 8.
   x compatibility notice, PHP 8.0 and above treats undefined array key access as
   a warning, whereas PHP 7.x was more lenient about it.
 * This warning is cosmetic and shouldn’t affect functionality, it’s logged by debug
   log but won’t break the page or any backup operations. That said, it’s something
   we want to clean up properly on our end.
   If you’re on PHP 8.x, you may also see
   this go away if you disable debug log, since it surfaces notices that would otherwise
   be silently logged.Thanks again for the heads up!
