Actions on Google responds with "Sorry, I didn't get any response."

Question

I am following this code lab Facts about You: Build a conversational app for the Google Assistant

I had it working once but must have done something wrong because now all. To be 100% clear i have deleted everything on my pc downloaded the code from Git again deleted the project in actions console deleted the project in api.ai. This is the result of a completely new install. I have not changed anything in the code lab.

"Sorry, I didn't get any response."

The request apears to be sending corectly

From actions test:

{
  "conversationToken": "CiZDIzU5Ym...",
  "debugLevel": 1,
  "inputType": "KEYBOARD",
  "locale": "en-US",
  "mockLocation": {

  },

Response returned to actions

{
  "audioResponse": "//NExAARAA...",
  "conversationToken": "CiZDIzU5Ym...",
  "expectUserResponse": true,
  "response": "Sorry, I didn't get any response.",
  "visualResponse": {
    "visualElements": []
  }
}

I must be missing something. Firebase is receiving the request its just not responding correctly.

That error on appears if your web hook doesn't provide a response to the assistant. The cloud function has been triggered or has timed out and not returned the JSON back to assistant to parse. Check to see what the output of the cloud function is and check it against the API.AI web hook format here https://developers.google.com/actions/reference/v1/apiai-webhook

It should look something like this:

{
  "speech": "...",  // ASCII characters only
  "displayText": "...",
  "data": {
  "google": {
      "expect_user_response": true,
      "is_ssml": true,
      "permissions_request": {
         "opt_context": "...",
         "permissions": [
            "NAME",
            "DEVICE_COARSE_LOCATION",
            "DEVICE_PRECISE_LOCATION"
          ]
      }
    }
    },
   "contextOut": [...],
}
