Why do i get the Error cannot post /login using express and passportjs? - express

Question

When i make a post request containing the user data to log in, i get the response: Cannot post /login.
What is really weird about this is that you can see trough logging that the request get processed.
I was using postman and a html form to test and both didnt worked.
When i have a failure in the passport.js file it gets logged.
.
Thats my server.js file (shortened):
const express = require("express");
const cors = require("cors");
const flash = require("express-flash");
const passport = require("passport");
const session = require("express-session");
//app configuration
const app = express();
require("dotenv").config();
const initializePassport = require("./config/passport-config");
initializePassport(
passport,
require('./models/User')
)
app.use(
session({
secret: "Janniks whatsapp Klon",
resave: false,
saveUninitialized: false,
})
);
app.use(passport.initialize());
app.use(passport.session());
//For accepting post from data
const UserRouter = require("./api/User");
app.use(flash());
app.use(express.json());
app.use(bodyarser.urlencoded({ extended: true }));
app.use(
cors() //{ origin: "http://localhost:3000", origin: "http://localhost:3000" }
);
app.use("/user", UserRouter);
app.post('/login', passport.authenticate('local', {
sucessRedirect: 'http://localhost:3000/login',
failureRedirect: 'http://localhost:3000/login',
failureFlash: true
}),
)
and thats my passport-config.js file
const passport = require('passport')
const LocalStrategy = require('passport-local').Strategy
const bcrypt = require('bcrypt')
//Password handle
function initialize(passport, User){
const authenticateUser = async(emailORnumber, password, done)=>{
//Find user with email or phone number
let user;
if(emailORnumber.includes('#')){
user = await User.findOne({ email: emailORnumber})
}else{
user = await User.findOne({ number: emailORnumber })
}
if(!user){
//User not found, error
console.log('User not found')
return done(null, false, { message: 'Falsches passwort oder falsche Handynummer' })
}
//Check if password is correct
try{
console.log('Checking password')
const isMatch= await bcrypt.compare(password, user.password);
if(!isMatch){
return done(null, false, { message: 'Falsches passwort'})
}else{
//If credentials are correct, return the user object
console.log('correct') //gets logged
return done(null, user)
}
}
catch(err){
console.log(err)
return done(err)
}
}
passport.use(new LocalStrategy({ usernameField: 'emailORnumber'}, authenticateUser)),
//Serialize user to store
passport.serializeUser((user, done)=>{
console.log('Serializing user') //gets logged
done(null, user.id)
})
//Deserialize user from store
passport.deserializeUser((id, done)=>{
console.log('Serializing user') //dont gets logged but there is no interaction
User.findById(id, (err, user)=>{
return done(err, user);
});
});
}
module.exports = initialize;
Thanks for all awnsers that can be provided!
