I guess we could add a guard for that so it blows up so we can find it

[bdraco]

I wonder if its actually be unloaded out from under it instead... hard to tell on this one

[jpbede]

It seems to me that cloud is causing this error. cloud and cast are the only two integrations that use async_create_catching_coro, which then calls catch_log_coro_exception, which uses coro_wrapper (as seen in the log above). I haven't been able to figure out what exactly is causing it there though.

[bdraco]

Maybe a CC is using it?

@Anto79-ops are you still seeing this on the latest beta?

[jpbede]

For my part, I can say that I still see it on b3. Will try booting in safe mode later.

[Anto79-ops]

Yes, I'm still seeing on b3.

[jpbede]

When I start in safe mode, I no longer see this message. So this is more likely to be caused by a CC.

[jpbede]

@Anto79-ops Do you use Spook?

[jpbede]

Yea, it is Spook. Found it, will create a PR for it.

[jpbede]

frenck/spook#647 should fix this, applied this to my prod and the log disappeared

[Anto79-ops]

~~Do you mind listing your CCs?

I have dyson, spook, spook inverse, node red, hass agent, hacs, extended openai, nest protect, and gas buddy.~~

Oh never mind, you found it and yes, i have spook....for some reason github didn't show the previous messages until I posted .

Thank you!

[jpbede]

You could try disable Spook, restart and see if the log messages disappear to confirm

[Anto79-ops]

thanks @jpbede
I can confirm your findings. Disabling spook and restarting, the log do not appear even 15 minutes in from restart.

[bdraco]

I'm going to close this one. Please continue at frenck/spook#647

[Anto79-ops]

Thanks all.
