Getting empty response with Sails.js

[dnish]

Hey guys, I'm using this plugin in combination with Sails.js. I'm using the following code:

video: function (req, res) {

    req.validate({
        id: 'string'
    });

    var id = req.param('id');

   //This is a normal collection with information to the gridfs document
    Videos.findOne(id).exec(function (err, found) {

        if (err || !found) return res.notFound();

        var options = {_id:found.video, root:'videos'};

        gfs.exist(options, function (err, found) {
            found ? console.log('File exists') : console.log('File does not exist');
        });

      var stream = gfs.createReadStream(options);
        console.log(stream);
        stream.on("readable", function() {
           stream.pipe(res);
        });

    });

}

He finds the file and giving me a "File exists" in my console, but I only get an white blank page as response. Any idea what I'm doing wrong?

//Edit: Well, I also get a 0 byte file if I'm writing to a file:

      var stream = gfs.createReadStream(options);

        console.log(stream);
        stream.on("readable", function() {

            var writer = fs.createWriteStream("test.mp4");

            stream.pipe(writer);
        });
