Is it possible that React Router v6 ProtectedRoute is failing to display any content?

My goal is to allow only authenticated users to access certain routes, such as the "/dashboard" route. However, I'm running into issues when attempting to render the protected route. The page appears to be white, and I'm not seeing any errors in the console. Here's my code: ProtectedRoute.js 

import { Outlet } from 'react-router-dom'
import { AppContext } from '../contexts/AppContext'
import Login from '../pages/Login';

const userAuth = () => {
  const { isAuthenticated } = useContext(AppContext);
  return isAuthenticated; 
}

const ProtectedRoute = () => {
  const isAuth = userAuth();
  return isAuth ?  : ;
}

export default ProtectedRoute;
App.js 

import React from 'react';
import { Route, Routes } from 'react-router-dom';
import Dashboard from './pages/Dashboard';
import Home from './pages/Home';
import Login from './pages/Login';
import ProtectedRoute from './utils/ProtectedRoute';

function App() {
    return (
        
            } />
            } />
            }>
                } />
            
        
    );
}

export default App;
I want to ensure that only authorized users can access certain routes, like "/dashboard." However, after implementation, the page remains blank without any error messages displayed.

It seems that you are trying to create a protected route in your React application. The code you provided looks correct. However, there are a few things you can check to ensure that the protected route is working as expected. Firstly, make sure that the isAuthenticated value is being set correctly in the AppContext. You can check this by logging the value of isAuthenticated in the console. Secondly, you can try wrapping your Routes component with a BrowserRouter component. This will ensure that the routing works correctly. 
import { BrowserRouter } from 'react-router-dom';

function App() {
    return (
        <BrowserRouter>
            <Routes>
                <Route path='/' element={<Home/>} />
                <Route path='/login' element={<Login/>} />
                <Route element={<ProtectedRoute/>}>
                    <Route path='/dashboard' element={<Dashboard/>} />
                </Route>
            </Routes>
        </BrowserRouter>
    );
}
Lastly, you can try using the useNavigate hook instead of the Outlet component in your ProtectedRoute.js file. Here's an example: 
import { useNavigate } from 'react-router-dom';
import { AppContext } from '../contexts/AppContext';
import Login from '../pages/Login';

const userAuth = () => {
  const { isAuthenticated } = useContext(AppContext);
  return isAuthenticated; 
}

const ProtectedRoute = () => {
  const navigate = useNavigate();
  const isAuth = userAuth();
  if (!isAuth) {
    navigate('/login');
    return null;
  }
  return <Outlet/>;
}

export default ProtectedRoute;
I hope this helps! Let me know if you have any other questions.

Based on the code you have provided, it seems like you are using React Router for routing in your application. You have a ProtectedRoute component which checks if the user is authenticated before rendering the Outlet or Login component based on the result. The issue you are facing might be because you are not providing a path for the ProtectedRoute component in the Route element. You can modify your App.js code as follows to see if this resolves your issue. 
import { Route, Routes } from 'react-router-dom';
import Dashboard from './pages/Dashboard';
import Home from './pages/Home';
import Login from './pages/Login';
import ProtectedRoute from './utils/ProtectedRoute';

function App() {
    return (
        <Routes>
            <Route path='/' element={<Home/>} />
            <Route path='/login' element={<Login/>} />
            <ProtectedRoute path='/dashboard' element={<Dashboard/>} />
        </Routes>
    );
}

export default App;
Also, make sure that you have wrapped your App component with the appropriate context provider so that the isAuthenticated value is available to the ProtectedRoute component.
