Does anyone know what's going on?

This works

    @view_config(route_name='configurationkeys_for_app', request_method="GET")
    def configurationkeys_GET(self):
        """ List all configurationkeys with GET method """
        app_id = self.request.swagger_data['id']
        if Application.get(app_id) is None:
            print_log(datetime.datetime.now(), 'GET', '/applications/%s/configurationkeys'\
                % app_id, 'Get configurationkeys', 'Failed')
            return self.createResponse(None, 400)
        app_conf_keys = ConfigurationKey.query().join(Application).filter(Application.id == app_id)
        return list(map(lambda _: _.as_dict(), app_conf_keys))

And this doesn't

    @view_config(route_name='configurationkey', request_method="GET")
    def configurationkeys_GET_one(self):
        """ Find and return one configurationkey by id with GET method """
        app_id = self.request.swagger_data['appid']
        confkey_id = self.request.swagger_data['ckid']
        confkey = get_conf_key_by_appid_and_ckid(app_id, confkey_id)
        if confkey is None:
            print_log(datetime.datetime.now(), 'GET',\
                '/applications/%s/configurationkeys/' % app_id
                + str(confkey_id), 'Get one configurationkey', 'Failed')
            return self.createResponse(None, 400)
        return confkey.as_dict()

Added routes are:

    config.add_route('configurationkeys_for_app', '/applications/{id}/configurationkeys')
    config.add_route('configurationkey', '/applications/{appid}/configurationkeys/{ckid}')
