empty object

[FiReBlUe45]

I have a problem when a query returns an empty object http://api.steampowered.com/ISteamUser/GetFriendList/v1/?key=XXXXXXXXXXXXXXX&format=json&steamid=76561198057531537&relationship=all

user.GetFriendList(optionalRelationship = 'all', '76561198057531537').done(function(result){ console.log(result) });
