CompactToken parsing failed with error code: 80049217 when using passport library to access Microsoft Graph API

Question

I am using 'passport-azure-ad-oauth2' npm module, to get an access token, which I could then pass to the MS Graph API.

passport.use(new AzureAdOAuth2Strategy({
    clientID: process.env.OUTLOOK_CLIENT_ID,
    clientSecret: process.env.OUTLOOK_SECRET,
    callbackURL: '/auth/outlook/callback',
},
    function (accesstoken: any, refresh_token: any, params: any, profile, done) {
        logger.info('Completed azure sign in for : ' + JSON.stringify(profile));
        logger.info('Parameters returned: ' + JSON.stringify(params));
        const decodedIdToken: any = jwt.decode(params.id_token);
        logger.info('Outlook Access Token:' + accesstoken);
        logger.info('Decoded Token: ' + JSON.stringify(decodedIdToken, null, 2));

        process.env['OUTLOOK_ACCESS_TOKEN'] = accesstoken;
        // add new user with token or update user's token here, in the database

    }));

And then, using '@microsoft/microsoft-graph-client' npm module, to fetch Calendar events from the Graph API as follows:

try {
    const client = this.getAuthenticatedClient(process.env['OUTLOOK_ACCESS_TOKEN']);
    const resultSet = await client
                .api('users/' + userId + '/calendar/events')
                .select('subject,organizer,start,end')
                .get();
    logger.info(JSON.stringify(resultSet, null, 2));
} catch (err) {
    logger.error(err);
}

getAuthenticatedClient(accessToken) {
    logger.info('Using accestoken for initialising Graph Client: ' + accessToken);
    const client = Client.init({
        // Use the provided access token to authenticate requests
        authProvider: (done) => {
            done(null, accessToken);
        }
    });

    return client;
}

However, however, using the accessToken provided on Successful Login, I get the following error : CompactToken parsing failed with error code: 80049217

Any suggestions what am I doing incorrectly ???

UPDATE : These are the scope I am using : 'openid,profile,offline_access,calendars.read'

UPDATE : After editing the scopes a bit, now I am getting the following error : Invalid Audience.

On decoding the token received at jwt.ms, this is the value for 'aud': "00000002-0000-0000-c000-000000000000"

Is it the case that passport-azure-ad-oauth2 is the wrong library for retrieving tokens for MS Graph API ?

Answer 1

According to my test, we can use the following code to get the access token. app.js

require('dotenv').config();
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var session = require('express-session');
var flash = require('connect-flash');
var passport = require('passport');
var OIDCStrategy = require('passport-azure-ad').OIDCStrategy;


// Configure simple-oauth2
const oauth2 = require('simple-oauth2').create({
  client: {
    id: process.env.OAUTH_APP_ID,
    secret: process.env.OAUTH_APP_PASSWORD
  },
  auth: {
    tokenHost: process.env.OAUTH_AUTHORITY,
    authorizePath: process.env.OAUTH_AUTHORIZE_ENDPOINT,
    tokenPath: process.env.OAUTH_TOKEN_ENDPOINT
  }
});
var users = {};

// Passport calls serializeUser and deserializeUser to
// manage users
passport.serializeUser(function(user, done) {
  // Use the OID property of the user as a key
  users[user.profile.oid] = user;
  done (null, user.profile.oid);
});

passport.deserializeUser(function(id, done) {
  done(null, users[id]);
});

// Callback function called once the sign-in is complete
// and an access token has been obtained
async function signInComplete(iss, sub, profile, accessToken, refreshToken, params, done) {
  if (!profile.oid) {
    return done(new Error("No OID found in user profile."), null);
  }


  // Create a simple-oauth2 token from raw tokens
  let oauthToken = oauth2.accessToken.create(params);

  // Save the profile and tokens in user storage
  users[profile.oid] = { profile, oauthToken };
  return done(null, users[profile.oid]);
}

// Configure OIDC strategy
passport.use(new OIDCStrategy(
  {
    identityMetadata: `${process.env.OAUTH_AUTHORITY}${process.env.OAUTH_ID_METADATA}`,
    clientID: process.env.OAUTH_APP_ID,
    responseType: 'code id_token',
    responseMode: 'form_post',
    redirectUrl: process.env.OAUTH_REDIRECT_URI,
    allowHttpForRedirectUrl: true,
    clientSecret: process.env.OAUTH_APP_PASSWORD,
    validateIssuer: false,
    passReqToCallback: false,
    scope: process.env.OAUTH_SCOPES.split(' ')
  },
  signInComplete
));
