R10 error on Heroku

Unable to deploy streamlit code with heroku.
Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
Please help

Same problem here. Please help

Any solution yet? Requesting help…Tried updating python version, made sure proc file and setup.sh file are correct. Couldn’t resolve the issue.

proc file:
web: sh setup.sh && streamlit run app.py
setup.sh:
mkdir -p ~/.streamlit/

echo "
[server]\n
port = $PORT\n
enableCORS = false\n
headless = true\n
\n
" > ~/.streamlit/config.toml

I could deploy my app through heroku CLI option without error…Proc and setup file are the same as mentioned above in my comment…steps followed through heroku CLI (myapp is the name of herokuapp which should be unique)

  1. $ heroku login
  2. $ cd your-proj/
  3. $ git init
  4. $ heroku git: remote -a myapp
  5. git add .
  6. git commit -am “comment for commit”
  7. git push heroku master
