Req.body of a twilio webhook request is undefined node js - node.js

Question

I tried following this twilio article:
https://www.twilio.com/blog/parsing-an-incoming-twilio-sms-webhook-with-node-js
The following is my server in its entirety
// Imports
const http = require('http')
const express = require('express')
const app = express()
const port = 80
const MessagingResponse = require('twilio').twiml.MessagingResponse;
// Static Files
app.use(express.static('public'))
// Set views
app.set('views', './views')
app.post('/sms', (req, res) => {
const twiml = new MessagingResponse();
// Access the message body and the number it was sent from.
console.log(req.IncomingMessage.body)
res.writeHead(200, {'Content-Type': 'text/xml'});
res.end(twiml.toString());
});
// Listen on port
app.listen(port, () => {
console.log(`Running on port ${port}`)
})
I have the webhook of my twilio phone posting to "http://{domain}.com/sms"
Every time I send a text to my twilio phone, I get the following error:
TypeError: Cannot read property 'body' of undefined

Answer 1

I don't think the req object has any property called IncomingMessage. Instead you could try:
console.log(`Incoming message from ${req.body.From}: ${req.body.Body}`);
So based on the twilio specs, the endpoint would look like:
app.post('/sms', (req, res) => {
const twiml = new MessagingResponse();
// Access the message body and the number it was sent from.
console.log(`Incoming message from ${req.body.From}: ${req.body.Body}`);
res.writeHead(200, {'Content-Type': 'text/xml'});
res.end(twiml.toString());
});
Since the message body is in the req.body.Body parameter, so console logging this property will show you the message text.

First answer is correct,
console.log(`Incoming message from ${req.body.From}: ${req.body.Body}`);
but I had to make sure to set the express urlencoding or else req.body came back as undefined.
app.use(
express.urlencoded({
extended: true,
})
);

I'm not sure if this is correct but when I'm using express I use req.body.IncomingMessage
console.log(req.body.IncomingMessage)
