Code for index.js
const express = require('express')

const app = express()

    authRequired: false,

  const oidc = req.oidc

  let { token_type, access_token, isExpired, refresh, expires_in } = oidc.accessToken;

  const refreshToken = oidc.refreshToken;

  if (isExpired()) {
    try {
      const { access_token, expires_in } = await refresh({refreshToken: refreshToken});

    } catch(error) {

    "Access Token": `${token_type} ${access_token}`,
    "Refresh Token": `${refreshToken}`,
    "Expires in": expires_in

app.get('/profile', requiresAuth(), (req, res) => {

const port = process.env.PORT || 3000
app.listen(port, () => {
  console.log(`Listening on port ${port}`)
  • Problem:

I am trying to implement authentication using rotating refresh tokens. For the first time, I authenticate using my email and password. In response, I get an access token and refresh function. After my access token expires, I use the refresh function to get another access token.

This works perfectly until the refresh token expires. After the refresh token expires, I would like a new refresh token to be used to grant an access token.

I can see from req.oidc.refreshToken that when a new access token is returned, a new refresh token is also returned. Not sure how to use that, or any other function so that before an old refresh token expires. A new refresh token can be used to grant access tokens.
