On Google Nest Hub:
If I attempt to scroll through a long list response while the Dialogflow Agent is still speaking, it triggers the default fallback. If I wait for the Agent to stop speaking, I'm able to scroll up/down on the list with no problems.
A similar bug is reported here for someone using the Jovo Google Action framework: https://github.com/jovotech/jovo-framework/issues/6051
In attempt to recreate the error, I made a new Actions on Google Project using boilerplate code for the list response.
This error did in fact show up again. No problems when I test it on a phone/tablet. Seems to be unique to the Google Home Hub.
Here's where I got the boilerplate code: https://developers.google.com/assistant/conversational/responses#list2
Here's the code I used to recreate the error:
'use strict';
const {
dialogflow,
List,
Image
} = require('actions-on-google');
const functions = require('firebase-functions');
const app = dialogflow({
debug: true
});
app.intent('List1', (conv) => {
if (!conv.screen) {
conv.ask('Sorry, try this on a screen device or select the ' +
'phone surface in the simulator.');
return;
}
conv.ask('This is a long conversational response. If you try to scroll/browse the list response while I\'m talking right now, it\'s going to trigger the default fallback. You have to wait until I\'m done talking to successfully scroll the list.');
// Create a list
conv.ask(new List({
title: 'List Title',
items: {
// Add the first item to the list
'1': {
