[TYPO3-english] FE User Disabled Projects shows error

[HOJA M A]

Hi Guys,

I've a project that uses several fields in a form. Among the fields two of them are storing FE user data. If I disables an FE User from TYPO3 Backend I could not able to edit the record. It shows an error

[ error occurred while trying to call TYPO3\PitsProjects\Controller\PitsprojectsController->editAction().]

Can anyone please help me to sort it out.

NOTE: I've used TYPO3 Repository / Persistence Object for this.

Thanks in advance!.
