nodejs passport-azure-ad redirect to failureRedirect - node.js

Question

Hello i am trying to understand and apply "passport-azure-ad" function which i found on https://learn.microsoft.com/en-us/graph/tutorials/node?tutorial-step=1 to my own web applicaton.
Instead of "hbs"template engine what they use in the tutorial i use "jade". I registered the application in Azure. When running the web-application I and noticed that the signin function is working (redirected to the login page of Microsoft to enter my credentials). But when i leave the credentials page it returns to the http://localhost:3000/error instead of **http://localhost:3000/succes ** what i expected.
Can you please help me?
Below i put the javascript files:
app.js
require('dotenv').config();
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');

}
});
// Configure passport
// In-memory storage of logged-in users
// For demo purposes only, production apps should store
// this in a reliable storage
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);
}
try{
const user = await graph.getUserDetails(accessToken);
if (user) {
// Add properties to profile
profile['email'] = user.mail ? user.mail : user.userPrincipalName;
console.info(users)
}
} catch (err) {

}
// Create a simple-oauth2 token from raw tokens
