Using Cosmos provider OrderBy owned property throw exception togheter with OData

Bug: OrderBy owned property (Cosmos)

Include your code

Sorry, I don’t have any small reusable code. I have tested odata with a runtime data set and it works with child properties. (without ef core), Looking at the stacktrace I don’t think there is any issues with odata.

    public class ChildModel
    {
        public int Number { get; set; }
    }

    public class ParentModel
    {
        public string Id { get; set; }
        public string Name { get; set; }
        public ChildModel Child{ get; set; }
        public string PartitionKey { get; set; } = nameof(ParentModel);
    }
  

    await db.ParentModels
   .WithPartitionKey(nameof(ParentModel))
   .AsNoTracking()
   .OrderBy(p => p.Child.Number).ToArrayAsync()
  

Stacktrace output

@XzaR90 if you could submit a runnable code sample - similar to the one @smitpatel posted above - that would be the best way forward.

@smitpatel Did you try with “int”? I am using 5.0.9 and it still does not work for me.
