Your stack trace shows that the problem comes from formidable, not multer.

A quick search on formidable's github open issues gives this.

Maybe try to run npm update.

Finally got the solution, need to add bodyParser for parse request bodies in a middleware.

var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

it will work for Url Encoded requests. For Multi-part request, need to add middle ware like multer.
