Use the HandlerError class to return an error status from your intent handler code. Classes such as DeviceManager return an instance of HandlerError when an error occurs. For other errors that may occur in your app, you can create a new instance and return a rejected Promise.

identifyHandler(request: IntentFlow.IdentifyRequest):
    Promise<IntentFlow.IdentifyResponse> {
  const scanData = request.inputs[0].payload.device.udpScanData;
  if (!scanData) {
    const err = new IntentFlow.HandlerError(request.requestId,
        ErrorCode.INVALID_REQUEST, 'Scan data not found');
    return Promise.reject(err);
  }
  ...
}

Errors returned by your app are visible in your cloud project logs. For more details, see the error logging developer guide.
