Possible null reference argument for parameter 'value' in 'T? JsonConvert.DeserializeObject<T>(string value)'.

Nullability of reference types in type of parameter 'snapshotData' of 'bool SnapshotFileHandler.TryReadSnapshot(SnapshotFullName snapshotFullName, out string? snapshotData)' doesn't match implicitly implemented member 'bool ISnapshotFileHandler.TryReadSnapshot(SnapshotFullName snapshotFullName, out string snapshotData)' (possibly because of nullability attributes).

Nullability of type of parameter 'value' doesn't match overridden member (possibly because of nullability attributes).

Nullability of type of parameter 'existingValue' doesn't match overridden member (possibly because of nullability attributes).

Nullability of type of parameter 'text' doesn't match overridden member (possibly because of nullability attributes).

Nullability of type of parameter 'value' doesn't match overridden member (possibly because of nullability attributes).

Nullability of type of parameter 'existingValue' doesn't match overridden member (possibly because of nullability attributes).

Cannot convert null literal to non-nullable reference type.
