Sendgrid Inbound Webhook Sending Empty Body - meteor

Question

Trying to get Sendgrid's Inbound Parse Webhook following their instructions here
Using Meteor and Iron Router. I am capturing the request but the request body is empty. I'm following this tutorial https://sendgrid.com/blog/receive-inbound-email-meteorjs/ and https://sendgrid.com/blog/control-home-lighting-parse-webhook/, but when I do a console.log(this.request.body), it's returning an empty object {}.
I've also tried getting text (this.request.text), html, from, to, subject, but nothing. The only thing I've had success getting is this.request.headers.
The Sendgrid activity dashboard does show that the emails are being parsed, and I am clearly receiving them, but the body is empty. This is unexpected behaviour and I'm not sure how to troubleshoot. Can anybody point me in the right direction? Thanks. Here's a sample request.

So, the Parse API makes a POST request to an endpoint of your choosing, but the data is encoded as a multipart/form-data. I recommend using Formidable which is an express middleware to parse the data, and then extract it via a regular key-value lookup. Here's some sample code to help you out:
var form = new formidable.IncomingForm();
form.parse(req, function(err, fields, files){//do something here})
