Unsupported content type Image/PNG

Question

I am trying to upload a image file on server using NodeJS busboy and I am getting this error:

Service Listening for request on: 8080
Error: Unsupported content type: image/png
    at Busboy.parseHeaders (D:\ImageUploadService\node_modules\busboy\lib\main.j

Below is my code:

app.post('/uploadImage',function(req,res){
    var alias=req.query.alias;
    var imagetype=req.query.imagetype;  //can be media/profile
    var busboy = new Busboy({ headers: req.headers });
    busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
        var saveTo = ".\\Images\\"+alias+"\\"+imagetype+"\\"+filename;
        if (fs.existsSync(saveTo)) {
            file.pipe(fs.createWriteStream(saveTo));
        }
        else{
            fs.mkdir(".\\Images\\"+alias+"\\"+imagetype,function(err){
                 saveTo=".\\Images\\"+alias+"\\"+imagetype;
                 file.pipe(fs.createWriteStream(saveTo));
            });
        }   
    });
    busboy.on('finish', function() {
      res.writeHead(200, { 'Connection': 'close' });
      res.status(200).end();
    });
    return req.pipe(busboy);
});

I am trying to make request using POSTMAN REST CLIENT.

Is this a problem from client or do I have to make chnages in the code. Please note that I've mentioned Content-Type: image/png on the client(postman).

Side question: Also, I there a way I can store the image as thumbs ??

Busboy only parses application/x-www-form-urlencoded and multipart/form-data requests. If you're sending raw file data, you have to handle that manually (and that's trivial because there is no parsing involved).

Postman supports HTML form submissions, just use that with the `Content-Type` of `multipart/form-data` and add your file to the form. – mscdex Sep 30 '14 at 18:37
Maybe you could post a screenshot of your Postman settings/setup? – mscdex Sep 30 '14 at 19:49
I tried it using fiddler and it worked. Dont know what it is not working with postman? – writeToBhuwan Sep 30 '14 at 21:55
