The problem

When using the assist functionality in HA I’ve noticed that my logs are filling up with the following error:

Logger: homeassistant.components.websocket_api.http.connection Source: components/websocket_api/connection.py:150 Integration: Home Assistant WebSocket API (documentation, issues) First occurred: 21:20:07 (5097 occurrences) Last logged: 21:27:46

In the space of running one command I had over 3000 errors. I’m not exactly sure if something isn’t working, but I shouldn’t be getting 3000+ errors.

Seeing the same, only difference being that it's only "1" for me at the end of the error (no "2", "3", etc). Also, this started showing up right after I upgraded core to 2023.11.3 this morning.

Core 2023.11.3

I have the same error, it has to do something when using the companion app on MacOS using the assist functionality. It works when using home assistant assist from a browser, but not from the companion app.

I use nabu casa btw

I am also seeing this issue when using Assist from Firefox on MacOS. I have no issues when using the Android companion app for Assist though.
