google action conversation exit: not waiting for user response - actions-on-google

Question

I am trying to seek user feedback at the end of a google action session using actions sdk.
As per the Actions documentation (https://developers.google.com/actions/assistant/conversation-exits), I have set the cancel intent
"conversations" : {
...
"inDialogIntents": [
{
"name": "actions.intent.CANCEL"
},
...
and in my functions code I am calling a SimpleResponse as below:
app.intent('actions.intent.CANCEL', (conv, input) => {
conv.close(new SimpleResponse({
speech: 'Kindly rate between 1 and 5,
text: 'Rate between 1 and 5'
}));
});
When the user says goodbye, the above code gets called. The speech is heard and text displayed but the conversation immediately exits with an earcon.
The documentation mentions that the system will wait for 2 seconds before exiting but it seems to do so immediately. Is there a way to get this working? Thanks

It's not quite clear to me what you'd like to achieve. First of all, as long as you're using conv.close() method, you are ending the conversation. If you want to keep the mic open, you need to use conv.ask() method. But I'm not sure id you can use conv.ask() with actions.intent.CANCEL, because that event is there to get the user out, not to keep the conversation going. But I'm not %100 sure, you need to try it.
If what you're trying to achieve is something like this:
User: cancel
System: How would you rate our interaction?
User: Good.
earcon
Then, in my humble opinion, you probably shouldn't (and as I said you probably can't) do it. The docs clearly state that the purpose for custom exit behavior is:
to cleanup your fulfillment logic and respond to the user one last time.
Also, the docs doesn't say the system will wait for the user response for 2 second. It says the execution of the request (the time out for your fulfillment) is 2 seconds. Plus; if a user is canceling mid-conversation, chances are that the interaction was unsuccessful anyway. I'd rather create feedback dialog turns that are connected to the fallback intents and happy path(s).
Still, try to use conv.ask() instead and let me know if that works. (And please let me know by commenting.) Either case, though, I'd consider getting the feedback some other way.
