This error shows when I log in with the admin profile. I declared the admin at but still giving me the error.
Kernel.php:

protected $routeMiddleware = [
        'auth' => AppHttpMiddlewareAuthenticate::class,
        'admin' => AppHttpMiddlewareAdminMiddleware::class,
        'auth.basic' => IlluminateAuthMiddlewareAuthenticateWithBasicAuth::class,
        'bindings' => IlluminateRoutingMiddlewareSubstituteBindings::class,
        'can' => IlluminateAuthMiddlewareAuthorize::class,
        'guest' => AppHttpMiddlewareRedirectIfAuthenticated::class,
        'throttle' => IlluminateRoutingMiddlewareThrottleRequests::class,
    ];

and this is how web.php route looks like:

Route::middleware(['web', 'auth', 'admin'])->group(function () {
    Route::get('/admin', [AdminDashboardController::class, 'index'])->name('admin.dashboard');

I tried to use some AI tools but no results. Please help me with this
