Yesterday I changed my app URL in Heroku and also updated the webhook URL in FB login and Messenger Webhook but all of a sudden my bot Send to Messenger plugin stopped working. I checked the Webhook error logs and it shows that The requested URL returned error: 400 Bad Request

I tried changing the staging app URL the same as what I did in my production but my staging didn't stop working.
Both are using the same updated source code and deployed in Heroku.
