Handling webhook resposnse

How to handle webhook response

I am using wix Editor

I created an automation for an on order created event. My trigger is Order placed & my action is Send via webhook. I am sending the webhook to my post_order function in the Wix http-functions.js file. Though when the response is sent the body comes back empty. Why is my body returning emptry as when i direct the webhook to send to an example third party like webhook.site I am able to see the response that is sent for when an order is placed.
