Hey @Amanweb200

Can you post what error is it showing?
You can check the application logs by following these steps -

  • Open the Heroku website
  • Click on your app name
  • Click on More (top right corner)
  • View Logs

Additionally, can you also post your repo link?

Hey @Amanweb200

You need to make changes to your and Procfile

In the file you are dynamically trying to make changes to the configurations file inside the .streamlit folder when the folder does not exist at all. Here are the changes that you need to make -

mkdir -p ~/.streamlit/
echo "\
headless = true\n\
port = $PORT\n\
enableCORS = false\n\
" > ~/.streamlit/config.toml

Now, in the Procfile, you are asking Heroku to load file when it boots which exists in the root folder but you are setting its path inside the .streamlit folder. Here are the required changes -

web: sh && streamlit run

It is working well after making these changes.
