Nested WL.api call breaks

Problem The problem I'am having is that when i try to call a second WL.api from my parent, because i'am in need of the data output from the first api, the script seem to break. I don't get any error response from the second api. If someone could point me in the right direction with this problem I would be grateful.

Note: The first call to fetch the folders work and i get the wanted data. It's when i try to make the second call to fetch the files in the wanted folder that breaks.

My function is is called from a button's onClick event, this is my function:

function getFolders() {
       WL.api({
             path: "me/skydrive/files",
             method: "GET"
       }).then(
             function(response) {
               var folders = response.data;
               $.each(folders, function () {
                      var folder = this;
                      if (folder.name == 'FooBar') {
                         WL.api({
                            path: "/" + folder.id + "/files",
                            method: "GET"
                            }).then(
                                function(response2) {
                                    var files = response2.data;
                                    $.each(files, function() {
                                        var file = this;
                                        if (file.name == 'Foo') {
                                            alert(file.id);
                                        }
                                    });
                                },
                                function(responseFailed) {
                                    alert(responseFailed.error.message);
                                }
                          );
                        }
                    });
                },
                function(responseFailed) {
                    alert(responseFailed.error.message);
                }
            );  
}

Solution

Maybe you must check that you are receiving a folder or an album, and not a file, because I think that you cant browse for files in a file.

i.e

if (folder.type == 'folder' || folder.type == 'album')
    if (folder.name == 'FooBar') { //do the call }

before you calling the next api request.

Try if that helps
