Describe the bug

• TYPO3 v12.4.14

I got for each contentelement in listview this error:
PHP Warning: Undefined array key "colPos" in /flux/Classes/Integration/Overrides/BackendLayoutView.php line 118)

Screenshots

Additional context
This fixed the wrong behavior for me:

Original Code
$parentRecordUid = ColumnNumberUtility::calculateParentUid((integer) $this->record['colPos']);

Changed Code
$parentRecordUid = ColumnNumberUtility::calculateParentUid((int) ($this->record['colPos'] ?? 0));

Please merge it to next patch-level.
