Response error execute intent but google home mini/ google home app always return success

I response error execute intent for offline devices like the following code:

const {smarthome} = require('actions-on-google');
const app = smarthome();
// ...
app.onExecute((body, headers) => {
  // TODO Send command to device
  return {
    requestId: body.requestId,
    payload: {
      commands: [{
        ids: ["456"],
        status: "ERROR",
        errorCode: "offline"
      }]
    }
  };
});

But google home mini/ google home app say “you got it, turn xxx on/off”.

Ok, i have the same problème, and i finally find the solution. You’r ids [] need to contain string not int so just use id.toString. It work for me.
