Error Response with Google Smart Home (Thermostat)

Question

I am unable to understand the syntax of Json for errors I have tried

return {
        "requestId": self.request_id,
        "payload": {
            "commands": [{
                "ids": [self.device_id],
                "status": "OFFLINE",
                "errorCode": "deviceTurnedOff"
            }]
        }
    }

and

return {
        "requestId": self.request_id,
        "payload": {
            "errorCode": "authFailure",
            "commands": [{
                "devices":  [{
                    "ids": [self.device_id],
                    "status": "ERROR",
                    "errorCode": "deviceTurnedOff"
                }]
            }]
        }
    }

and

return {
      "requestId": self.request_id,
      "payload": {
        "errorCode": self.error_code
      }
    }

none of above syntax are working, most of the time google home says that your actions is performed but I am returning error Json there.

I have read google actions documentation but failed to understand.

Answer 1

I have come up with a few payloads and have managed to get them successfully triggering errors using the AoG simulator after consulting the docs .

Node.js snippet:

let resBody = {
    requestId: request.requestId,
    payload: {
        "errorCode": "notSupported"
    }
}
response.status(200).json(resBody);

Are you sure that the requestId is the same from the smart home request? How are you testing these errors?
