Upload Image from triggerio to express.js fails - express

Question

I'm trying to post a file from a mobile triggerio app to a nodejs service. The request hits the post method, but the fails because the form object is null in the request obj.
(TypeError: Cannot call method 'complete' of undefined)
I've adapted the code from the accepted answer in this post : Uploading images using Node.js, Express, and Mongoose
This is my current nodejs code:
var express = require('express')
, form = require('connect-form');
var app = express.createServer(
form({ keepExtensions: true })
);
app.post('/fileupload', function(req, res, next){
//req. form is nulL
req.form.complete(function(err, fields, files){
if (err) {
next(err);
} else {
console.log('\nuploaded %s to %s'
, files.image.filename
, files.image.path);
res.redirect('back');
}
});
req.form.on('progress', function(bytesReceived, bytesExpected){
var percent = (bytesReceived / bytesExpected * 100) | 0;
process.stdout.write('Uploading: %' + percent + '\r');
});
});
app.listen(process.env.PORT);
console.log("express started");
And this is my upload method in triggerio:
function uploadFile (file){
forge.request.ajax({
url: 'http://resttrigger.aykarsi.c9.io/fileupload',
type: 'POST',
files: [file],
fileUploadMethod: 'raw',
dataType: 'json',
success: function (data) {
forge.logging.log("success " + data);
},
error: function (e) {
forge.logging.log("error " + e);
}
});
}

Using fileUploadMethod: 'raw' might be the problem here: it means that the request body is just a binary blob, rather than the multipart-encoded form which your node code expects.
For reference, here is a minimal handler that will save uploaded files into /tmp:
exports.upload = function(req, res){
var filename = '/tmp/' + new Date().getTime();
console.log(JSON.stringify(req.files));
// replace "test" with your actual form field name
fs.readFile(req.files["test"].path, function (err, data) {
fs.writeFile(filename, data, function (err) {
res.send({filename: filename});
});
});
};
