When i create a relation and save the extension, i get this error and the changes are not saved (no relations were saved inside the model.php e.g.)

when i remove the relation, i can save without eror.

with the branch (not Tag !!!) dev-typo3-12-reactjs this issue never seems to occur, so I suppose it's not relevant anymore.
