Messages list in CollectingOutputChannel always empty

Rasa version: 1.0.6

Rasa X version (if used & relevant): 0.19.0

Python version: 3.7.3

Operating system : Windows 10 1709 Build 16299.1146

Issue: Messages list in CollectingOutputChannel always empty. I have attempted to modify the Google Assistant connector example from this link to work with Sanic in Rasa 1.0 (the Sanic server works). However, the above-mentioned output channel never returns any reply from Rasa. Please let me know what is the issue.

Error (including full traceback):

Message handling no reply for user message 'Hello there'.
list index out of range

Command or request that led to error:

@google_webhook.route("/webhook", methods=["POST"])
async def receive(request):

    payload = request.json
    sender_id = payload["user"]['userId']
    intent = payload['inputs'][0]['intent'] 			
    text = payload['inputs'][0]['rawInputs'][0]['query']

    try:
        if intent == "actions.intent.MAIN":
            message = "<speak>Hello! <break time=\"1\"/> Welcome to the Rasa-powered Google Assistant skill. You can start by saying hi."
        else:
            out = CollectingOutputChannel()
            new_message = UserMessage(text,out,sender_id,input_channel=self.name())
            #NO EFFECT
            await on_new_message(new_message)
            responses = [m["text"] for m in out.messages]
            message = responses[0]
    except LookupError as e: 
            logger.error("Message handling no reply for user message '{}'.".format(text))
            logger.error(e)
            message = "RASA_NO_REPLY"
