- Introduced a using directive for exceptions in DocumentCreateReadSQL.cs.
- Enhanced CreateParmas method with try-catch for base64 conversion errors, throwing BadRequestException on failure.
- Added switch statement in HistoryController.cs to manage Related property in ReadHistoryQuery, setting flags for receiver and sender.
