            .expand('Complex', o => {
                o.select('Id', 'Name')
                    .expand('Internal', i => {
                        i.select('Description', 'Requester')

            .orderBy('Status', OrderBy.Desc);

        let x = new HttpHeaders();
        this.generatedUrl = `http://localhost/PrivateKey?${query.compile()}`;
