Rasa x fails to bind to PORT on heroku app

Question

I have dockerized my rasa x chatbot and deployed it in heroku, but the application keeps on crashing.

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

My docker files looks like :

FROM ubuntu:18.04
ENTRYPOINT []
RUN apt-get update && apt-get install -y python3.7 python3-pip && python3 -m pip install --no-cache --upgrade pip==20.2 && python3 -m pip install rasa-x==0.39.3 --extra-index-url https://pypi.rasa.com/simple
ADD . /app/
RUN chmod +x /app/start_services.sh
CMD /app/start_services.sh

and my start_services script is:

cd app/
# Start rasa server with  model
rasa x --no-prompt -p $PORT

I have tried running by removing $PORT as well but it doesn't work.

Note: To deploy to heroku, I created dockerfile in rasa directory where rasa was installed using rasa init and deployed it using heroku container:push web

Any help would be appreciated.

You use -port when running Rasa. For Rasa X try --rasa-x-port

rasa x --rasa-x-port $PORT
