I recently started noticing the following error when I restart Hass. These errors started after I was playing around with some scripting and Sonos - I deleted all the scripts but the error still comes up after a restart.
I tried searching first and saw people with similar errors but not any fixes. I would love some help interpreting this error, could this be caused by device discovery? (I’m trying to figure out how to approach a fix).
