Get data from routes server trough heroku-deployed app

Hey everyone,

I have a streamlit app deployed trough heroku which should access the data at the routes http-server from pyRevit trough get-requests. Unfortunately, the access is always denied or an empty response is returned, when a json is expected.

I write the data i want in routes of the http-routes API as described in the Documentation.
When i access it in the browser, everything is fine. When i run the streamlit app local, the get request to the routes server works perfect.

What am i missing?

Any help is super appreciated!

Best regards,
