Sort by expanded relationship property

[gertaMng]

Hello,

I have defined models BlacklistAgenti and Agente, which have the following relationship blacklistAgenti -> belongsTo(agenti)
Now I'm having problems sorting blacklistAgenti by the property of an extended relationship:
http://localhost:8080/odata/blacklistAgenti?$expand=agente&$orderby=agente/nome%20desc&$count=true&$top=10&$skip=0

The error I get is as follows:

code: "invalid_sort_property"
details: []
innererror: {}
message: "The orderby parameter specified properties (agente/nome) that did not exist"
target: null

It seams that it is totally ignoring the relationships.
I tried ordering by nested properties:
http://localhost:8080/odata/blacklistAgenti?$expand=agente($select=nome;$orderby=nome%20asc)&$count=true&$top=10&$skip=0
which doesn't throw any exception but doesn't return a collection sorted in the desired order.

The last approach i followed is by adding additional property to $appends using accessories, but still same as in #791 it tries to get it from the sql query.

Im currently using Laravel 11.0 + flat3/lodata 5.32

Thank you in advance.
