actions on google, Oauth account Linking - oauth-2.0

Question

I have been trying to connect an assistant action to my backend server
I am using my own Oauth server and followed the instructions on
https://developers.google.com/actions/identity/oauth2?oauth=code
I am using actions_intent_Sign_in for my dialogflow event intent (like https://actions-on-google.github.io/actions-on-google-nodejs/classes/conversation_helper.signin.html)
when i use my action to sign in, i get the login window to my server, i do the account linking and i can see that i generated the tokens on my server but i cant find the token in (conv.user.access.token)
and this is the code for my intent using "actions on google sdk "
'use strict';
var _ = require('lodash');
var path = require('path')
var express = require('express')
var http = require('http')
const bodyParser = require('body-parser');
var expressApp = express().use(bodyParser.json());
var server = http.createServer(expressApp).listen(3000)
const {
dialogflow,
SignIn
} = require('actions-on-google');
const app = dialogflow({
debug: true,
clientId: '7b4a6dfc-4b35-11e9-8646-d663bd873d93'
});
app.intent('Start Sign-in', conv => {
conv.ask(new SignIn());
});
app.intent('Get Sign-in', (conv, params, signin) => {
console.log("get sign in ");
console.log(JSON.stringify(signin));
if (signin.status === 'OK') {
const access = conv.user.access.token
console.log("the access token is " + access);
conv.ask('Great, thanks for signing in! What do you want to do next?');
} else {
conv.ask('I wont be able to save your data, but what do you want to do next?.');
}
});
and the response comes back as
{"#type":"type.googleapis.com/google.actions.v2.SignInValue","status":"OK"}
the access token is undefined
Response {
"status": 200,
"headers": {
"content-type": "application/json;charset=utf-8"
},
"body": {
"payload": {
"google": {
"expectUserResponse": true,
"richResponse": {
"items": [
{
"simpleResponse": {
"textToSpeech": "Great, thanks for signing in! What do you want to do next?"
}
}
]
}
}
}
}
}
the user object of conv has only this data
"user": {
"raw": {
"lastSeen": "2019-03-20T12:46:23Z",
"locale": "en-US",
"userId": "okdhyeGSk5tofgLjEepIUrA6mmewCESY8MjklZRPvQJgv6-uybfPobwdfgtrGZJ3bE2sM9ninhst"
},
"storage": {},
"_id": "okdhyeGSk5tofgLjEepIUrA6mmewCESY8MjklZRPvQJgv6-uybfPobwdfgtrGZJ3bE2sM9ninhst",
"locale": "en-US",
"permissions": [],
"last": {
"seen": "2019-03-20T12:46:23.000Z"
},
"name": {},
"entitlements": [],
"access": {},
"profile": {}
}
i dont know where the access/refresh token can be found or if there is any requirement for the post to send from my oauth server that i missed

Answer 1

so finally i managed to get it working with the help of Actions on Google Support Team
the problem was me having another google account logged-in in another tab, even though i had the AoG and dialogflow agent connected with the same account
tried all using incognito window and it works
