IBM Watson integration with Twilio SMS bot

I'm using this sample code here: https://github.com/watson-developer-cloud/botkit-middleware.

I have essentially setup twilio, watson conversation with an active workflow already. My problem is that when sending text message to twilio, twilio sends a POST request to a webhook that I exposed using ngrok. But when my code picks up the POST request it's being received with empty body. no text, user, from, to. or whatever. I'm using Twilio SMS Bot and not the Twilio IPM Bot.

from botkit

Initializing Botkit v0.6.11

info: ** Serving webhook endpoints for Twilio Programmable SMS at: localhost:5000/sms/receive
Twilio bot is live
Client server listening on port 5000

{ raw_message: {},
  _pipeline: { stage: 'receive' },
  text: undefined,
  user: undefined,
  channel: undefined,
  from: undefined,
  to: undefined,
  timestamp: 1521132895282,
  sid: undefined,
  type: 'message_received',
  watsonData: { output: { text: [] } } }

from ngrok

changes made to leverage twilio sms instead of ipm.

const configuration = {
  account_sid: process.env.TWILIO_ACCOUNT_SID,
  auth_token: process.env.TWILIO_AUTH_TOKEN,
  twilio_number: process.env.TWILIO_NUMBER
};

const Botkit = require('botkit');

const controller = Botkit.twiliosmsbot(configuration);

var bot = controller.spawn({});

Twilio developer evangelist here.

I noticed the server in question only parses incoming requests as JSON. Twilio sends webhooks in the format application/x-www-form-urlencoded so you need to tell bodyParser to parse those types of requests too.

I'd add the following to server.js

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

Then you should be able to read the body of Twilio requests.
