Unhandled exception – (ERRORE) /srv/homeassistant/lib/python3.8/site-packages/aiohttp/web_protocol.py

Hello everybody,
I’ve been getting this error for a few days now. HA works fine apparently, but it’s annoying to find the error in the log every time.
Does anyone know what it is?
Thanks & Regards

I have the same exact problem, same error log all the way, character by character.

I was so proud of having a clean log on my install for quite some months, no errors whatsoever, but now this one keeps popping up every now and then, very annoying indeed.

I’m on:
Home Assistant OS 6.1
