ImportError: cannot import name 'SessionInfo' from 'streamlit.web.server.server' #1024

I am using ngrok to connect to virtual server environment and run into this error

This import error occurs since the last update. And I am able to solve it by downgrading streamlit to 1.11.0

Complete log:

Thank you for the report.

It seems that this problem has occurred since streamlit==1.12.1

I will fix it.
