Header.js
import React, { createContext, useContext } from 'react' import { Link } from 'react-router-dom' import AuthContext from '../context/AuthContext' const Header = () => { let { name } = useContext(AuthContext) return ( <div> <Link to="/">Home</Link> <span> </span> <Link to="/login">Login</Link> <h1>Hello {name}</h1> </div> ) } export default Header
App.js
import './App.css'; import { BrowserRouter, Routes, Route, } from "react-router-dom"; import HomePage from './pages/HomePage'; import LoginPage from './pages/LoginPage'; import Header from './components/Header'; import PrivateRoute from './utils/PrivateRoute' import AuthProvider from './context/AuthContext'; function App() { return ( <div className="App"> <BrowserRouter> <AuthProvider> <Header /> <Routes> <Route path="/" element={ <PrivateRoute> <HomePage /> </PrivateRoute>} /> <Route path="/login" element={<LoginPage />} /> </Routes> </AuthProvider> </BrowserRouter> </div> ); } export default App;

Answer
import AuthProvider from './context/AuthContext';
Instead of the above, you have to import the AuthProvider
like below since you have used named export for AuthProvider
in the AuthContext.js
file.
import { AuthProvider } from './context/AuthContext';
