How to attach a file to Fb.api?

[dfb243fda]

Hello, I want to upload a picture to an album. Here is my code:
FB.api(folderId + '/photos', 'post', {"source": fs.createReadStream(filePath)}, function (res) {
if(!res || res.error) {
console.log(!res ? 'error occurred' : res.error);
return;
}
console.log('Post Id: ' + res.id);
});
In this case I get the error from facebook: (#324) Requires upload file.

This should work now in 1.1.0-alpha1.
