Streamlit app crashes

Deployment

I’ve been trying to deploy my streamlit app on heroku and it keeps crashing. I wonder what’s the issue. Any help will be much appreciated. Thanks!

heroku logs --tail is pasted below:

Hi @Blues1998, welcome to the Streamlit community!

Unfortunately, your log doesn’t provide a whole lot of information here. Would you be able to post more of the log, or a minimal example to help us understand your use case?

Best,
Randy

I’ve also got same problem.
So far solution I got -

  1. Check server.js file for port connection, because Heroku uses it’s random port, so better use const const PORT = process.env.PORT || 8000
  2. Check package.json for postbuild if you haven’t used ‘npm run build’
  3. Extra spacing can produce such types of error.
  4. Check your production enviroment properly. etc.
