Node.js Canno't GET or POST users from route - node.js

Question

I am doing backend login and register project with Nodejs and Express but somehow I cannot login or register anymore or even fetch data from my usersRoute and I don't know why. I am lost..
My index.ts file:
import express from "express";
const https = require("https");
import cors from "cors";
import mongoose from "mongoose";
const app = express();
//import Routes
const usersRoute = require("./routes/users");
//Middleware
app.use(cors());
app.use(express.urlencoded({ extended: false }));
app.use(express.json());
//Route middlewares
app.use("api/users", usersRoute);
//connect to db
mongoose
.connect("mongodb://localhost:27017/containerlab")
.then(() => {
console.log("connected to database");
})
.catch(() => {
console.log("connection failed!");
});
const PORT = 5000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
My users.ts file
import express from "express";
const router = express.Router();
const User = require("../models/User");
const {
registerValidation,
loginValidation,
} = require("../middleware/validation");
const bcrypt = require("bcryptjs");
const jwt = require("jsonwebtoken");
const secretKey = "f43g34gergeerg";
const verifyToken = require("../middleware/verifyToken");
//REGISTER user
router.post("/register", async (req, res) => {
//VALIDATE DATA from Joi, before register
const { error } = registerValidation(req.body);
if (error) return res.status(400).send(error.details[0].message);
//check if user is alredy in database
const emailExist = await User.findOne({ email: req.body.email });
if (emailExist) return res.status(400).send("Email already exists");
//encrypt password z bcryptjs modulom
const salt = await bcrypt.genSalt(10);
const hashPassword = await bcrypt.hash(req.body.password, salt);
//create new user
const user = new User({
email: req.body.email,
password: hashPassword,
});
try {
//save new user
const savedUser = await user.save();
//res.json(savedUser);
res.json({ user: user._id });
} catch (err) {
res.json({ message: err });
}
});
//LOGIN
router.post("/login", async (req, res) => {
//VALIDATE DATA from Joi, before register
const { error } = loginValidation(req.body);
if (error) return res.status(400).send(error.details[0].message);
//check if email exists.. če NE obstaja mail dobiš da ne ustreza
const user = await User.findOne({ email: req.body.email });
if (!user) return res.status(400).send("Email doesn't exist");
const validPass = await bcrypt.compare(req.body.password, user.password);
if (!validPass) return res.status(400).send("Invalid password");
//create and send a json web token
const token = jwt.sign({ _id: user._id }, secretKey, { expiresIn: "1h" });
res.header("auth-token", token).send(token);
res.send("Logged in!");
});
//get users
router.get("/", async (req, res) => {
try {
const users = await User.find();
res.json(users);
} catch (err) {
res.json({ message: err });
}
});
module.exports = router;
And my verifyToken.ts middleware
const jwt = require("jsonwebtoken");
const secretKey = "f43g34gergeerg";
module.exports = (req: any, res: any, next: any) => {
const token = req.header("auth-token");
if (!token) return res.status(401).send("Access denied");
try {
const verified = jwt.verify(token, secretKey);
req.user = verified;
next();
} catch (err) {
res.status(400).send("Invalid token");
}
};
Somehow I can't fetch ANY data from users.ts (from usersRoute). Thank you for your help
