Getting response [] for every intent

I am trying to run Rasa from Docker after running the rasa build for every message I am getting . I have used this deployment - Deploy Rasa in Docker - Stack Overflow to Dockerize the application.

It would be good to see the debug log start-up messages because I think that your model is not loading based on this message:

There is no trained model for 'DIETClassifier': The component is either not trained or didn't receive enough training data.

I would confirm that the model is accessible and loading at startup.
