RefreshToken not present in tokenSET - node.js

Question

I am trying to connect with the api hubstaff to which I have set up my authentication using auth0 and express as my backend. To know about the info about the logged in user I need to send the token object via the API.
By some research I have gotten to this point:
const {
Issuer,
TokenSet
} = require('openid-client');
const fs = require('fs');
const jose = require('jose');
// constants
const ISSUER_EXPIRE_DURATION = 7 * 24 * 60 * 60; // 1 week
const ACCESS_TOKEN_EXPIRATION_FUZZ = 30; // 30 seconds
const ISSUER_DISCOVERY_URL = 'https://account.hubstaff.com';
// API URl with trailing slash
const API_BASE_URL = 'https://api.hubstaff.com/';
let state = {
api_base_url: API_BASE_URL,
issuer_url: ISSUER_DISCOVERY_URL,
issuer: {}, // The issuer discovered configuration
issuer_expires_at: 0,
token: {},
};
let client;
function loadState() {
return fs.readFileSync('./configState.json', 'utf8');
}
function saveState() {
fs.writeFileSync('./configState.json', JSON.stringify(state, null, 2), 'utf8');
console.log('State saved');
}
function unixTimeNow() {
return Date.now() / 1000;
}
async function checkToken() {
//console.log('state.token.access_token', state.token.access_token);
if (!state.token.access_token || state.token.expires_at < (unixTimeNow() + ACCESS_TOKEN_EXPIRATION_FUZZ)) {
// console.log('Refresh token');
state.token = await client ? .refresh(state.token);
// console.log('Token refreshed');
saveState();
}
}
async function initialize() {
console.log('API Hubstaff API');
let data = loadState();
data = JSON.parse(data);
if (data.issuer) {
state.issuer = new Issuer(data.issuer);
state.issuer_expires_at = data.issuer_expires_at;
}
if (data.token) {
state.token = new TokenSet(data.token);
}
if (data.issuer_url) {
state.issuer_url = data.issuer_url;
}
if (data.api_base_url) {
state.api_base_url = data.api_base_url;
}
if (!state.issuer_expires_at || state.issuer_expires_at < unixTimeNow()) {
console.log('Discovering');
state.issuer = await Issuer.discover(state.issuer_url);
state.issuer_expires_at = unixTimeNow() + ISSUER_EXPIRE_DURATION;
console.log(state.issuer);
}
client = new state.issuer.Client({
// For personal access token we can use PAT/PAT.
// This is only needed because the library requires a client_id where as the API endpoint does not require it
client_id: 'Z',
client_secret: 'J',
});
saveState();
console.log('API Hubstaff initialized');
}
async function request(url, options) {
await checkToken();
let fullUrl = state.api_base_url + url;
return client ? .requestResource(fullUrl, state.token, options);
}
function tokenDetails() {
let ret = {};
if (state.token.access_token) {
ret.access_token = jose.JWT.decode(state.token.access_token);
}
if (state.token.refresh_token) {
ret.refresh_token = jose.JWT.decode(state.token.refresh_token);
}
return ret;
}
module.exports = {
initialize,
checkToken,
request,
tokenDetails
};
// COntroller
const { response } = require('express')
const api = require('../util/hubstaffConnect.util');
const testConnected = require('../util/testhubstaff.util');
const usersGet = async (req, res = response) => {
await api.initialize();
const response = await api.request('v2/organizations',{
method: 'GET',
json: true,
});
console.log('response', response);
if(response != null){
const body = JSON.parse(response);
res.json({
organizations: body.organizations || []
});
}
};
Although when I go to the address localhost:8080/oauth/api/organizations I ran into an error:
I do realise this is regarding missing tokens which won't let me get the user's information.
