Getting html response instead of json rasa x server mode (docker) - docker

Question

I created the rasa x server in server mode using docker-compose (link, https://rasa.com/docs/rasa-x/installation-and-setup/install/docker-compose). I want to get intent and entities so I am hitting this URL from postman (https://2286950d1621.jp.ngrok.io/model/parse) with text. But I'm getting an HTML response instead of a JSON response.

Answer 1

If you want to hit the Rasa Open Source server specifically, add /core to the endpoint -- so here: https://2286950d1621.jp.ngrok.io/core/model/parse
The /core tells the nginx proxy which service to send your request to. If you want to hit the Rasa X api, you should add /api.
What you are seeing currently is the Rasa X UI response, which is the default container (which is why you can log into the UI on the base url directly)
