It might be possible that the component doesn’t work anymore. In the Readme it says “Compatible Rasa Core Versions: 1.0” and the last update to the repository has been in February. We are currently at Rasa Open Source 1.10.
When you send a message in the UI, what log output do you get in the terminal where you executed python -m rasa run --m ./models --endpoints endpoints.yml --port 5005 -vv --enable-api? The debug output there might give you a hint about what’s going wrong.
I do not get any error message in that but yeah maybe its the versions. I have decided to not continue with it for the meanwhile. Thank you for your help though
