For Flutterflow firestore collection getting exception NoSuchMethodError: Class 'RegisteredDevicesRecord' has no instance method 'toJson' for autogenerated code

I have created Firestore Collection as below

Flutterflow has generated below code

class RegisteredDevicesRecord extends FirestoreRecord {
RegisteredDevicesRecord._(
DocumentReference reference,
Map<String, dynamic> data,
) : super(reference, data) {
_initializeFields();
}

// "serial_number" field.
String? serialNumber;
String get serialNumber => serialNumber ?? '';
bool hasSerialNumber() => _serialNumber != null;

// "user_name" field.
String? userName;
String get userName => userName ?? '';
bool hasUserName() => _userName != null;

// "locker_name" field.
String? lockerName;
String get lockerName => lockerName ?? '';
bool hasLockerName() => _lockerName != null;

// "userId" field.
String? userId;
String get userId => userId ?? '';
bool hasUserId() => _userId != null;

// "geofence_data" field.
List? geofenceData;
List get geofenceData => geofenceData ?? const [];
bool hasGeofenceData() => _geofenceData != null;

// "gps_timer" field.
String? gpsTimer;
String get gpsTimer => gpsTimer ?? '';
bool hasGpsTimer() => _gpsTimer != null;

// "live_location" field.
LatLng? liveLocation;
LatLng? get liveLocation => liveLocation;
bool hasLiveLocation() => _liveLocation != null;

// "reserved1" field.
String? reserved1;
String get reserved1 => reserved1 ?? '';
bool hasReserved1() => _reserved1 != null;

// "reserved2" field.
String? reserved2;
String get reserved2 => reserved2 ?? '';
bool hasReserved2() => _reserved2 != null;

// "battery" field.
String? battery;
String get battery => battery ?? '';
bool hasBattery() => _battery != null;

// "reserved3" field.
String? reserved3;
String get reserved3 => reserved3 ?? '';
bool hasReserved3() => _reserved3 != null;

void initializeFields() {
serialNumber = snapshotData['serial_number'] as String?;
_userName = snapshotData['user_name'] as String?;
_lockerName = snapshotData['locker_name'] as String?;
_userId = snapshotData['userId'] as String?;
_geofenceData = getStructList(
snapshotData['geofence_data'],
GeofenceStruct.fromMap,
);
_gpsTimer = snapshotData['gps_timer'] as String?;
_liveLocation = snapshotData['live_location'] as LatLng?;
_reserved1 = snapshotData['reserved1'] as String?;
_reserved2 = snapshotData['reserved2'] as String?;
_battery = snapshotData['battery'] as String?;
_reserved3 = snapshotData['reserved3'] as String?;
}

]);

@OverRide

}

Now whenever i try to pass this parameter while navigating to some other screen

Exception has occurred.
NoSuchMethodError (NoSuchMethodError: Class 'RegisteredDevicesRecord' has no instance method 'toJson'.
Receiver: Instance of 'RegisteredDevicesRecord'
Tried calling: toJson())

I understand there is no toJson method in RegisteredDevicesRecord class ,i dont want to change as it is auto generated

This was working fine till now on both Flutter Flow Test Mode and Local Code download as well but suddenly (19March) it started giving above exception and error as below in Test Mode
