Python Script to Web App Using Heroku and Streamlit

Question

I am attempting to create a web app to heroku.

It says that it deploys successfully but when I try to open it I get an error saying to check the console log.

There I find the following error code:

at=error code=H14 desc="No web processes running" method=GET path="/" host=name_name.herokuapp.com request_id=40cff699-28b5-4ea7-985b-c135dc8a526b fwd="174.16.132.201" dyno= connect= service= status=503 bytes= protocol=https

After searching around it appears to be a problem with my procfile. I have tried switching between 'web' and 'worker' but both give me the same error (above). Other peoples procfiles look very different to mine but I don't know enough about them to know what to change.

My current procfile:

worker: sh setup.sh && streamlit run name_name.py

Could you post a reproducible code? – ferdy Apr 10 '22 at 23:36 — ferdy, Apr 10 '22 at 23:36

Sample Procfile, note it must be capital P.

The app.py is the script filename.

web: sh setup.sh && streamlit run app.py

My script file is named app.py and Procfile has a capital P. – Matt Apr 10 '22 at 22:34
Use web and not worker. – ferdy Apr 10 '22 at 23:31
