Laravel Error 404 Beginner 28 views

NotFoundHttpException

The requested URL does not match any defined route.

Explanation

NotFoundHttpException is thrown when no route matches the incoming request URL. Unlike ModelNotFoundException which means a route matched but the record wasn't found, this means no route was defined for the URL at all. This commonly happens after changing route definitions, when visiting URLs with incorrect casing, or when route groups have path prefixes you forgot about. Laravel returns a 404 status code by default for this exception.

Common Causes

Route not defined for the URL
Incorrect route group prefix
Stale route cache
URL casing mismatch
Routes file not loaded in RouteServiceProvider

Solution

Run php artisan route:list to see all defined routes and verify your URL matches one of them. Check for typos in route definitions and URLs. Ensure route group prefixes are correct. Verify that your routes file is being loaded (check RouteServiceProvider). If the route existed before, check if a cache is stale by running php artisan route:clear. For SPA applications, ensure your catch-all route is defined for client-side routing.

Code Example

// This route doesn't exist, causing NotFoundHttpException
// GET /api/users/profile

// Define the route properly
Route::get('/api/users/profile', [UserController::class, 'profile']);

// For SPAs, add a catch-all route
Route::get('/{any}', function () {
    return view('app');
})->where('any', '.*');

// For API versioning, ensure prefix matches
Route::prefix('api/v1')->group(function () {
    Route::get('/users', [UserController::class, 'index']);
});
// Must access as /api/v1/users, not /api/users
