Error when turning off a Slimproto grouplayer.

[fibergm]

Hi,
i have a problem with my Slimproto groupplayer.
Everytime it want to turn off the groupplayer it throws an Error. This wasnt a problem a few months back, but now it is breaking my HASS automations.

To recreate the issue:
Restart MASS->Turn off the Slimmproto Groupspeaker
This should throw an error like the one in the attached logs.
MASS_Logs.txt

This line out of the logs seems important to me.

Im currently running MASS 2.3.6 with HASS 25.1.2, Supervisior 24.12.3 and OS 14.1

This was fixed in 2.4.0b12. Let us know if not fixed for you.

I have the same problem here when switching OFF a player group:

'set' object has no attribute 'set'

So all of my media automations in HA dosn't work.

I am on the HA Addon 2.3.6. How to update to 2.4.0b12? Is this a Beta?

Hi @frank2604.
You can b in 2.4.0b12 stands for beta.

You can install the beta normally over the addon manager in HASS. But adding it.
You should take care that you dont have them running at the same time.

After the comment from @OzGav. I switched to the the beta channel. I worked stable this far.
Please be aware that you need to set up music libarys and paths again, as the betat channel is like reinstalling MASS.
