Passport Local Strategy returns not found - node.js

Question

I'm trying to make a register/login with node, express and mongoose. I want to register and login users and if they aren't logged in they can't retrieve data from the api.
To make the login and register i have been watching this tutorial: Link it isn't as addecuate for my needs because half of the efforts and code goes into the ejs but i have been okay until the passport login.
I have created my local strategy in config/passport.js:
const LocalStrategy = require("passport-local").Strategy;
const bcrypt = require("bcryptjs");
const User = require("../models/user");
module.exports = function (passport) {
passport.use(
new LocalStrategy({ usernameField: "email" }, (email, password, done) => {
User.findOne({ email: email })
.then((user) => {
if (!user) {
return done(null, false, {
message: "That email is not registered",
});
}
bcrypt.compare(password, user.password, (err, isMatch) => {
if (err) console.log(err);
if (isMatch) {
return done(null, user);
} else {
done(null, false, { message: "Incorrect Password" });
}
});
})
.catch((err) => console.log(err));
})
);
passport.serializeUser((user, done) => {
done(null, user.id);
});
passport.deserializeUser((id, done) => {
User.findById(id, (err, user) => {
done(err, user);
});
});
};
My app.js looks like this:
const express = require("express");
const cors = require("cors");
const usersRouter = require("./routes/users");
const passport = require("passport");
const session = require("express-session");
require("dotenv").config();
const app = express();
require("./config/passport")(passport);
const connectDB = require("./db/connect");
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use(
session({
secret: "*****",
resave: true,
saveUninitialized: true,
})
);
app.use(passport.initialize());
app.use(passport.session());
app.use(cors());
app.use("/api/v1/users", usersRouter);
const PORT = process.env.PORT || 5000;
const start = async () => {
try {
await connectDB(process.env.MONGO_URI);
app.listen(PORT, console.log(`Server is listening on port: ${PORT}....`));
} catch (error) {
console.log(error);
}
};
const notFound = require("./middleware/notFound");
app.use(notFound);
start();
My users router looks like this:
const express = require("express");
const router = express.Router();
const { postRegister } = require("../controllers/register");
router.route("/register").post(postRegister);
const { postLogin } = require("../controllers/login");
router.route("/login").post(postLogin);
module.exports = router;
The register works perfectly, but the login controller doesn't. Each time i post to that endpoint instead of getting a succesMessage or failureMessage i get the page not found router that is called at the end of app.js, i checked if the router calls the login function via a console log and it does. Here is the code for the login controller:
const passport = require("passport");
const postLogin = (req, res, next) => {
console.log("The function has been triggered");
passport.authenticate("local", {
successMessage: "Login authenticated",
failureMessage: "Login failed",
})(req, res, next);
};
module.exports = {
postLogin,
};
Why don't I get the responses from the login controller or my local strategy and instead i get page not found when the Login controller actually works?
