Https://<appname> returns EMPTY response

I deployed my rasa bot on Heroku using docker. Now when I m using URL/model/parse I m getting all the intents and their scores but not getting the response and if I go with webhooks/rest/webhook it’s giving me an empty response (an empty array). Plz, refer to the below images. Although I ran the rasa server locally, in that case, webhooks/rest/webhook is working fine but after deployment, it’s not. plz refer to the below screenshots and help me
