Twilio Gather params Digits undefined

I'm going through this tutorial to collect digit input: https://www.twilio.com/docs/voice/tutorials/how-to-gather-user-input-via-keypad-node-js

The request.body is undefined so I can't seem to find the input. When I try request.params it is empty though in my Twilio dash board I can see the params are in the Post request from my gather action.

const fs = require('fs');
const botSpeak = require('./bot_speak/scripts.json');
const VoiceResponse = require('twilio').twiml.VoiceResponse;

const app = express();

// Returns TwiML which prompts the caller to record a message
app.post('/welcome', (request, response) => {
  // Use the Twilio Node.js SDK to build an XML response
  const twiml = new VoiceResponse();
  //read scipts from .json

  const gather = twiml.gather({
    numDigits: 1,
    action: '/gather'
  });

  gather.say(botSpeak.hello + botSpeak.continue);

  //if no response
  twiml.say(botSpeak.bye);

  // Render the response as XML in reply to the webhook request
  response.type('text/xml');
  response.send(twiml.toString());
});

app.post('/gather', (request, response) => {
  // Use the Twilio Node.js SDK to build an XML response
  const twiml = new VoiceResponse();

  // If the user entered digits, process their request
  console.log(request.body);
  if (request.body.Digits) {
    switch (request.body.Digits) {
      case '1':
        twiml.say('You selected sales. Good for you!');
        break;
      case '2':
        twiml.say('You need support. We will help!');
        break;
      default:
        twiml.say("Sorry, I don't understand that choice.").pause();
        twiml.redirect('/welcome');
        break;
    }
  } else {
    // If no input was sent, redirect to the /voice route
    twiml.redirect('/welcome');
  }

  // Render the response as XML in reply to the webhook request
  response.type('text/xml');
  response.send(twiml.toString());
});

// Create an HTTP server and listen for requests on port 3000
app.listen(3000);

console.log('Server serving on port 3000');

You need body-parser middleware. Try adding this.

// Body Parser Middleware
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
