Streamlit hosted con GCP Cloud run auto-creating GCE instances

Hi guys,

We have deployd a Streamlit app on GCP Cloud Run, but somehow it is automatically creating GCE instances. It seems to happen after a GET on the endpoint /_stcore/stream returning 101 (which seems not to be a backend action). As for what i have researched it can mean that it switched from HTTP requests to websocket in order to keep a connection live and the VM has the purpose to mantain this connection. How can I avoid it? Any tips?
