Sorting by sub objects

Assume I have the following schema:

var Car = {
   id: 'int',
   make: 'string',
   model: 'string',
};

var Person = {
   id: 'int',
   first_name: 'string',
   last_name: 'string',
};

var Passenger = {
   id: 'int',
   person: {type: 'Person'},
   car: {type: 'Car'},
};

If I do the following, I get the error Property ‘person.last_name’ does not exist on object type ‘Passenger’.

realm.objects('Passenger').sorted('person.last_name')

Is my syntax incorrect, or is sorting by sub-objects not supported? If it’s not supported, are there plans to support it?

It will be added but isn’t yet. This issue is for keeping track of it.

Support for this was added to core in realm/realm-core#1969 / realm/realm-core#2011.
