Typo3 10.4.37, PHP 7.4
When inserting a new CE into a gridelement, an error is thrown:
Argument 2 passed to GridElementsTeam\Gridelements\Backend\ItemsProcFuncs\SysLanguageUidList::checkForAllowedLanguages() must be of the type int, string given, called in typo3conf/ext/gridelements/Classes/Backend/ItemsProcFuncs/SysLanguageUidList.php
I changed the call of the function in line 42:
$this->checkForAllowedLanguages($params['items'], (int)$params['row']['tx_gridelements_container']);
This fixed the problem.
