I am using OData against the MongoDB IQueryable collection and it works fine but when I try to sort by a nullable field it breaks with: only fields are allowed in a $sort when ordering by a nullable field
If I convert that field to not nullable it works fine.
api/TimeTracking/ItemType?$orderBy=ModifiedAt => error when nullable
api/TimeTracking/ItemType?$orderBy=ModifiedAt => working when not nullable
IMongoQueryable<T> query = queryOptions == null? entities.AsQueryable() : queryOptions.ApplyTo(entities.AsQueryable()) as IMongoQueryable<T>;
Error:
Exceptions.ErrorHandlingMiddleware:Error: Only fields are allowed in a $sort.
System.NotSupportedException: Only fields are allowed in a $sort.

Did anyone have a similar experience? Is there a workaround for this?
