Hi @sindhumallya, welcome to the Streamlit community!! :wave: :partying_face:

Thanks for sharing your code repo. The problem is likely due to your Procfile. Try removing the file extension from Procfile.txt to Procfile. Once you remove the .txt extension from your Procfile, recommit and push your code to Heroku.

Let us know if that helps!

Happy Streamlit’ing! :balloon:

Hi, I am new to streamlit. I recently built an app which I was able to use locally. But I encountered an error when I wanted to deploy on heroku. Here is the link to the repo:

Below is the error:
at=error code=H10 desc=“App crashed” method=GET path="/" host=mental-health-diagnostic-app.herokuapp.com request_id=f567cd7d-27ce-4d0a-b59e-2a0a56c9f8c3 fwd=“102.89.32.102” dyno= connect= service= status=503 bytes= protocol=https

Pls help me with this. My Procfile is also without the .txt extension. So I do not know where the problem is from.
