Streamlit app crashes

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!

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
