WebSocket Error on App Load

[Kushanware]

The WebSocket error "Cached ForwardMsg MISS..." in Streamlit means that the frontend tried to fetch a message from the server cache, but the message was missing or expired. This usually happens when:

The app is reloaded too quickly

The server is under heavy load

There’s a mismatch between frontend and backend message sync

As a result, the app can't render correctly and shows a connection error.

@Kushanware There's indeed a lot of errors in the App currently due to being updated by multiple people in unsynced ways. I'm even surprised that the cloud deployment sidebar opened on your PC screen, it doesn't open on mine, LOL. But I never got this error though, at what point exactly did you see this? While refreshing the app?

Keep in mind sometimes these errors are also caused by Streamlit Cloud and are never seen again after the 1st time.

@Kushanware I have no problem in assigning this issue to you, I just wanted to know at what point did you encounter that error?
