TYPO3 12.4.5 - 16.08.23


Given select field item list was not found.

The Issue

This error happens when calling \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTcaSelectItem() on an item that is not a valid select item or does not have an items array.


My select item did not have an items array, adding an empty items array fixed it:

'type' => [
    'label' => 'Typ',
    'config' => [
        'type' => 'select',
        'renderType' => 'selectSingle',
        'items' => [],
