Nested resource promise empty array

[marekpw]

I'm doing something fairly simple and according to the documentation:

Restangular.one('titles', 1).getList('reviews').then(function(result) {
    console.log(result);
});

Unfortunately the result is always an empty array no matter what I do. When I look at the Network tab of Firefox, a correct GET request is fired and the response is also correct, but Restangular will just give me an empty array.
