Google Smart Home Agent responded Empty JSON

Question

I've hosted my fulfillment on AWS Lambda and when I test my Google Smart Home project and I try to EXEC a command StackDriver always logs: "Agent responded empty JSON" and Google Assistant says that my device is not available.

But running project locally, using ngrok, all works fine.

This is the command:

[
   {
      "devices":[
         {
            "id":"2272"
         }
      ],
      "execution":[
         {
            "command":"action.devices.commands.OnOff",
            "params":{
               "on":true
            }
         }
      ]
   }
]

And this is my response:

{
    "requestId": "11434449941327491819",
    "payload": {
        "commands": [
            {
                "ids": [
                    "2272"
                ],
                "status": "SUCCESS"
            }
        ]
    }
}

Based on CloudWatch logs, my function takes about 400 ms to answer, that is much less than 5 seconds of supposed timeout. So what I'm doing wrong?

Does this only occur for execute, or QUERY and SYNC? Is there something in AWS that causes the response to not be correctly translated to JSON? — Nick Felker, Dec 10 '18 at 19:29

Solved, I'm sorry, I was missing return statement before to call my promise chain!
