I’m new to coding and I’m currently working on a project where I’m encountering an error that’s preventing me from moving forward. Note that I had to add the Kernel.php file manually because it did not install when I created my Laravel project.

I am working with Laravel 11.

I am getting the error: Target class [admin] does not exist.

Here is web.php :

Route::get('/', function () {
return view('welcome');
});

Route::get('/dashboard', function () {
return view('back.dashboard');
})->middleware(['auth', 'verified', 'admin'])->name('dashboard');

Route::middleware('auth')->group(function () {
Route::get('/profile', [ProfileController::class, 'edit'])->name('profile.edit');
Route::patch('/profile', [ProfileController::class, 'update'])->name('profile.update');
Route::delete('/profile', [ProfileController::class, 'destroy'])->name('profile.destroy');
});

Here is Kernel.php :

protected $middlewareAliases = [
    'auth' => AppHttpMiddlewareAuthenticate::class,
    'auth.basic' => IlluminateAuthMiddlewareAuthenticateWithBasicAuth::class,
    'auth.session' => IlluminateSessionMiddlewareAuthenticateSession::class,
    'cache.headers' => IlluminateHttpMiddlewareSetCacheHeaders::class,
    'can' => IlluminateAuthMiddlewareAuthorize::class,
    'guest' => AppHttpMiddlewareRedirectIfAuthenticated::class,
    'password.confirm' => IlluminateAuthMiddlewareRequirePassword::class,
    'precognitive' => IlluminateFoundationHttpMiddlewareHandlePrecognitiveRequests::class,
    'signed' => AppHttpMiddlewareValidateSignature::class,
    'throttle' => IlluminateRoutingMiddlewareThrottleRequests::class,
    'verified' => IlluminateAuthMiddlewareEnsureEmailIsVerified::class,

    'admin' => AppHttpMiddlewareAdmin::class,
    'checkRole' => AppHttpMiddlewareCheckRole::class,
];

Here is the middleware Admin.php :

<?php

namespace AppHttpMiddleware;

use Closure;
use IlluminateHttpRequest;
use IlluminateSupportFacadesAuth;
use SymfonyComponentHttpFoundationResponse;

class Admin extends Middleware
{
    /**
     * Handle an incoming request.
     *
     * @param  Closure(IlluminateHttpRequest): (SymfonyComponentHttpFoundationResponse)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        $user = Auth::user();

        if ($user && str_contains($user->role, 'admin')){
            return $next($request);
        }

        abort(403, 'Accès non autorise');

    }
}

I have checked the name to see if I might have misspelled it, and I have verified that the files are in the correct folders. Everything seems to be in order.
