I am using custom allocation policy in device provisioning service (DPS) to register my iot device to iot hub, in which I am triggering azure function for the same.

Now if my function logic fails, I have to send the custom error message to a device, how would I do that? I know that we can send custom HTTP status code to the device in case of failure but I have to send some custom message along with that code.

Support for this is on the radar of the Azure Device Provisioning Service. Please look for an update over the next two months.

    We just announced support for this feature [here](https://azure.microsoft.com/en-us/updates/azure-iot-hub-device-provisioning-service-june-2019-update/). Just include a property called 'payload' in the response body with a JSON object as its value containing the error message. `{ "payload" : { "errorMessage" : "Encountered error xyz" } }` – Rajeev Vokkarne Aug 08 '19 at 22:42
