Streamlit Deployed in GCP

Hello guys. I was using streamlit as my front-end to convey data to user. And I was able to deploy my streamlit app into GCP (Google Cloud Platform). However, I am having a problem when a user is using the app, it keep refreshing!

I’ve done some research and found out that the app is not returning a request into gcp server.

Please advice on what should I do?. Thank you very much.
