multiparti image upload issue

Question

Please note before everything I'd like to mention I'm very new in mean stack. I got multiparty working in my code however the uploaded image is significantly smaller than original. Here is what I have in my controller and I appreciate if anyone can point me to the right direction. I'm guessing I'm not reading the stream completely and somehow I drop out:

var multiparty = require('multiparty'), fs = require('fs');
exports.postImage = function(req, res) {
var form = new multiparty.Form();
var data = "";
var fname = "";

form.on('part', function(part) {
if (part.filename)
{
        fname = '/Users/guest/Desktop/'+part.filename
        var writeStream = fs.createWriteStream(fname);
        part.pipe(writeStream);
} 
else 
{
        form.handlePart(part);
    }
});
form.on('close', function()
{
    console.log("Form closes ...");
});
form.parse(req);

I also noticed when the upload is done meaning when I get my message "Form closes ..." after a minute or so the following error is thrown:

events.js:72
        throw er; // Unhandled 'error' event
              ^
