Redirection fails when splitting in different files

[AndresMarotta]

I'm using passport.js authentication for different API's and works fine, but I want to separate the code for each one and I'm stuck calling passport.authenticate('facebook'). I'll put Facebook code for example.

This works:

const passport = require('passport');
const FacebookStrategy = require('passport-facebook').Strategy;
const fb = require('fb');

passport.use(new FacebookStrategy({
  clientID: 'XXXXXXXXXXXXXXXX',
  clientSecret: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
  callbackURL: "https://127.0.0.1/facebook/authCallback/"
}, function(accessToken, refreshToken, profile, cb) {
  return {accessToken, refreshToken, profile, cb};
}));

// Entry point
app.get('/authorize/:clientId/:network', passport.authenticate('facebook'));

app.get('/:network/authCallback', (request, response) => {
  // Some code here...
});

But when I try to split it in a different file, it never callback from passport.authenticate('facebook'):

sserve.js:

const authUtils = require('./utils/authUtils');

app.get('/authorize/:clientId/:network', (request, response) => {
  authUtils.authorize(request.params.clientId, request.params.network);
});

authUtils.js:

async function authorize(clientId, network) {    
  try {
    config = await databaseUtils.getConfig(clientId, network);

    if(typeof(config) !== 'undefined') {
      passport.use(new FacebookStrategy({
        clientID: config.appId,
        clientSecret: config.appSecretKey,
        callbackURL: 'https://127.0.0.1/' + network + '/authCallback/'
      }, function(accessToken, refreshToken, profile, cb) {
        return {accessToken, refreshToken, profile, cb};
      }));

      // It reachs to this point but never comeback...
      passport.authenticate(network);
    } else {
      throw new Error(network + ' is not configured');
    }
  } catch (e) {
    throw e;
  }
}

After some debug test, the problem seems to be that passport.authenticate(network) doesn't make redirection to callback URL.

If I add:

app.get('/authorize/:clientId/:network', (request, response) => {
  authUtils.authorize(request.params.clientId, request.params.network);
  console.log(1);
  next();
});

Console shows "1" and browser return 404 Not Found. Passport doesn't continue with the redirection process.
