[Bug]: Cloud Run IAP Load Balancer - Streamlit Websocket Issue

What happened?

My team (@JoshLuxton) and I stood up this sample app in cloud run, IAP and load balancer with the following instructions/documentation. We believe we followed all the instructions correctly, but we're encountering the following issue with trying to hit the public facing endpoint where the Streamlit app isn't able to complete the web socket connection. The page comes up blank:

And we get the following error on the console output.

Any help understanding this issue is appreciated, and I can provide more context if needed.

Relevant log output

My team switched to mesop since its version 0.12 didn't use web sockets. However, It's a lot more involved than streamlit.

I found a solution on another thread on config.toml
[server]
headless = true
enableCORS=false
enableXsrfProtection=false
enableWebsocketCompression=false
port = 8080
