This might have to do with having an input_boolean in your config. For me expose_by_default: true was causing troubles until i hid my input_boolean. After this syncing works fine. You can disable it by using entity_config. I think the errors above also disappear after hiding the input_boolean.

I've got the same problem. In previous versions (and maybe less devices) it worked perfectly.
Although I don't use any "input_boolean" in my configuration (only input_number).
I'll test which device is causing this and then report back.

Edit 1:
It seems that the bug with the input of booleans for GAssistant was already fixed in #13220.

For me the cause of the issue is a Philips Hue light in my hass configuration which is currently not plugged in making it unavailable (in hass). After plugging the light back in (and having any device available again), Google Assistant will link again. (My guess is that the google assistant component tries to find out the current color temperature of the lamp, but as the light is offline, hass can't get the color temperature and can not link with Google Assistant.)

[TheJulianJES]

For some reason the same error now also pops up when I turn off a light using GAssistant (not when turning on) but the light turns off.

[CedricGatay]

I can confirm the same issue, one lamp was unreachable that caused the sync to be misfunctionning.
Setting it to expose:false in the entity_config part allowed me to link / sync properly afterwards.

+1 ; expose:false on the disconnected light works as a workaround.

[MartinHjelmare]

Should be fixed in https://github.com/home-assistant/home-assistant/pull/13358.

Report back if this is still a problem in 0.66.

I'm getting this on Home Assistant 0.65.6 when trying to turn off an rgb // colortemp light.
The lamp still turns off but GAssistant says there was an error.
Turning on the light works without any problem and displays no errors at all.
-> Moved to #13381

@TheJulianJES please open a new issue. Your error is not exactly the same, so it's better to make a new issue.
