Streamlit app not working with heroku

Hi,
I’m using heroku to deploy my streamlit but post deployment it’s not showing anything and it gets timed-out. Here’s a snippet from log file:

I've added an ONNX model in my github repo (through git LFS) which is being loaded for inferencing. Locally it's working fine but on Heroku it isn't even reaching the model loading phase.

Any suggestions on how I should proceed ahead? Thanks in advance!
