Can't get sorting expression to evaluate correctly when using nested properties

Question

I have a linq query:

DbSet<GeneralGroup>()
.Where(...)
...
.Select(res => new GeneralGroupResult{ 
        Id = result.Id,        
        Statistics = new Statistics(
            res.GeneralCount,
            res.SpecificCount
        )        
    });

Once I run it in database context with .ToListAsync(), it works fine.

I need to support dynamic sorting. For example, when I receive Id, I generate the following expression:

{Param_0 => Convert(Param_0.Id, Object)}

Then I apply it to query with

query.OrderBy(expression)

So it becomes like this:

    ...
    .Select(res => new GeneralGroupResult{ 
            Id = result.Id,        
            Statistics = new Statistics(
                res.GeneralCount,
                res.SpecificCount
            )        
        })
   .OrderBy(namelessParameter{0} => (object)namelessParameter{0}.Id)

And that also works fine.

Same approach doesn't work with nested properties though. When I receive Statistics.SpecificCount and generate expression for it:

{Param_0 => Convert(Param_0.Statistics.SpecificCount, Object)}

I get this as evaluated expression:

        ...
        .Select(res => new GeneralGroupResult{ 
                Id = result.Id,        
                Statistics = new Statistics(
                    res.GeneralCount,
                    res.SpecificCount
                )        
            })
 .OrderBy(namelessParameter{0} => (object)namelessParameter{0}.Statistics.SpecificCount)

Which looks correct, but fails to translate to SQL with the following error:

Error creating query string: The LINQ expression 'DbSet<GeneralGroup>()
    .Where(...)
     ...
    .OrderBy(ti2 => (object)new Statistics(
        ti2.Inner.SpecificCount, 
        ti2.Inner.GeneralCount
    ).SpecificCount)' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to 'AsEnumerable', 'AsAsyncEnumerable', 'ToList', or 'ToListAsync'.

Any idea what am I missing here?
