Cannot read properties of undefined (reading 'jwt')

Hi there, I always get theis error in http://localhost:5000/api/auth/me. Got it also in another project but don't know how to fix...

getMe() : `import { generateTokenAndSetCookie } from "../lib/utils/generateToken.js"; import User from "../models/user.model.js"; import bcrypt from "bcryptjs";

export const signup = async (req, res) => { try { const { fullName, username, email, password } = req.body;

const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
if (!emailRegex.test(email)) {
  return res.status(400).json({ error: "Invalid email format" });
}

const existingUser = await User.findOne({ username });
if (existingUser) {
  return res.status(400).json({ error: "Username is already taken" });
}

const existingEmail = await User.findOne({ email });
if (existingEmail) {
  return res.status(400).json({ error: "Email is already taken" });
}

if (password.length < 6) {
  return res
    .status(400)
    .json({ error: "Password must be at least 6 characters long" });
}

const salt = await bcrypt.genSalt(10);
const hashedPassword = await bcrypt.hash(password, salt);

const newUser = new User({
  fullName,
  username,
  email,
  password: hashedPassword,
});

if (newUser) {
  generateTokenAndSetCookie(newUser._id, res);
  await newUser.save();

  res.status(201).json({
    _id: newUser._id,
    fullName: newUser.fullName,
    username: newUser.username,
    email: newUser.email,
    followers: newUser.followers,
    following: newUser.following,
    profileImg: newUser.profileImg,
    coverImg: newUser.coverImg,
  });
} else {
  res.status(400).json({ error: "Invalid user data" });
}

} catch (error) { console.log("Error in signup controller", error.message); res.status(500).json({ error: "Internal Server Error" }); } };

export const login = async (req, res) => { try { const { username, password } = req.body; const user = await User.findOne({ username }); const isPasswordCorrect = await bcrypt.compare( password, user?.password || "" );

if (!user || !isPasswordCorrect) {
  return res.status(400).json({ error: "Invalid username or password" });
}

generateTokenAndSetCookie(user._id, res);

res.status(200).json({
  _id: user._id,
  fullName: user.fullName,
  username: user.username,
  email: user.email,
  followers: user.followers,
  following: user.following,
  profileImg: user.profileImg,
  coverImg: user.coverImg,
});

} catch (error) { console.log("Error in login controller", error.message); res.status(500).json({ error: "Internal Server Error" }); } };

export const logout = async (req, res) => { try { res.cookie("jwt", "", { maxAge: 0 }); res.status(200).json({ message: "Logged out successfully" }); } catch (error) { console.log("Error in logout controller", error.message); res.status(500).json({ error: "Internal Server Error" }); } };

export const getMe = async (req, res) => { try { const user = await User.findById(req.user._id).select("-password"); res.status(200).json(user); } catch (error) { console.log("Error in getMe controller", error.message); res.status(500).json({ error: "Internal Server Error" }); } };

Don't even know what I should provide, sorry guys :/ Please help :)
