I have deployed my rasa chatbot in heroku but the application keeps crashing

I have dockerized my rasa chatbot and deployed it in heroku but the application keeps crashing… I am getting the following error: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

My other apps on heroku are not crashing but only the chatbot deployed in heroku is crashing.

Please help me…

I’m facing the same error while deploying rasa x chatbot on heroku

My docker file

FROM ubuntu:18.04
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

My start services script:

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.

Any help would be appreciated
