In your hold action, you appear to be calling the service ‘automation trigger’ and then instead of referencing an automation you are trying to call a bond.service
This is incorrect as bond.xx is not an automation. Also when calling the service ‘automation.trigger’ the extra data of ‘power state’ is not valid, this is exactly what the error message is stating.
I have no experience of the bond integration but the documentation appears to show what the service that you need to call is and what data is required for that service.
