Remove DialogFlow response in web-hook fulfillment

Is it possible to disable a response via webhook fulfillment? I'm using v2 of the DialogFlow API.

I'd like to add a 'live agent takeover' option to our bot -- but can't seem to disable a response when using fulfillment webhooks. I've tried responding to fulfillment with empty, false and null values for fulfillmentText or fulfillmentMessages, but to no avail. When I empty these values DialogFlow simply repopulates with the default text. 

{
  "fulfillmentText": "",
  "fulfillmentMessages": [],
  "outputContexts": [
    {
      "name": "projects/${PROJECT_ID}/agent/sessions/${SESSION_ID}/contexts/context name",
      "lifespanCount": 5,
      "parameters": {
        "param": "param value"
      }
    }
  ]
}

Suggestions?

It sounds like what you want in this case is to short-circuit Dialogflow directly and, instead of talking to the bot, talk to another person using the chat platform. That isn't really possible.

Dialogflow expects responses within about 5-10 seconds, or it thinks the webhook isn't responding at all. So while you could potentially build a bot that either gets internal replies if there is no live agent, and lets a person enter in replies otherwise, that person would have to reply quickly, and there isn't any way for that person to send multiple replies.

In the Dialogflow, you can scroll down the intent and disable the webhook if you do not want the response served from fulfilment.
