public class Deal

{
public DateTime CreatedOn { get; set; }
public DateOnly WonDate { get; set; {color:#bdbdbd}}

}

When do a filter :
IMongoCollection<Deal> var DealSet;
 
Query1:
 var deals1 = DealSet.AsQueryable().Where(x => x.CreatedOn != null && x.CreatedOn.Value.Year > 2024).ToArray();
 
Query2:var deals2  = DealSet.AsQueryable().Where(x => x.WonDate != null && x.WonDate.Value.Year > 2024).ToArray();

Query1 is working and Query2 throw an exception:

System.NotSupportedException: Serializer for System.DateOnly does not represent members as fields.

and the exception full stack:

System.NotSupportedException: Serializer for System.DateOnly does not represent members as fields.
