Unable to parse url encoded data in express

Question

I have this super simple server:

var app = require('express')();
var bodyParser = require('body-parser');

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/update', (req, resp) => {
  debugger;
  resp.send();
});

var server = app.listen(3000, function () {
  var host = server.address().address;
  var port = server.address().port;
  console.log('Example app listening at http://%s:%s', host, port);
});

Using postman, I am sending data to the server like this:

Postman screenshot

REPL shows me an empty body when the request is received:

> req.body
{}

I would expect the body to look something like this:

{
  "hello": "world"
}

Am I missing something obvious ? Probably ..

I just looked up debugger;. I never knew you could do that in node.js before. — Patrick Roberts

By choosing x-form-urlencoded below postman will send the Content-Type header for you, you dont need to specify it again yourself. You can see this by clicking the Preview button. So you're sending a duplicate Content-Type header which seems to trip up body parser.
