Unable to configure WhatsApp Webhook

Question: I configured the WhatsApp webhook using the free Replit URL and it worked as expected. However, when I deploy my Replit code (Autoscale plan) and try to configure WhatsApp webhook (in Meta for Developers dashboard) with my new deployment URL (https://...replit.app), I get the following error:

The callback URL or verify token couldn't be validated. Please verify the provided information or try again later.

Could you please help me overcome this issue?

And yes, the Callback URL and token are correct. Also, I just tested a GET request via Postman and it returned with the hub.challenge value, as expected.

facing the same issue, anyone able to help?
