我正在嘗試刪除一條記錄，但收到此錯誤，該類不存在，我正在使用 Laravel 6，我希望您的幫助或建議我不知道命名空間是否錯誤，盡管我已經檢查過并且沒問題，還是控制器中的某些內容我已經查看了這些方法，但找不到解決方案我附上了我的驅動程序文件和路徑控制器<?phpnamespace App\Http\Controllers\Admin;use App\Events\InstanceCreated;use App\Pesvial\City;use App\Pesvial\Instance;use App\Pesvial\Tracker;use App\Pesvial\TrackingServer;use Illuminate\Http\Request;use App\Pesvial\Vehicle;use App\Http\Controllers\Controller;use Auth;class TrackerController extends Controller{    public function __construct( )    {        $this->uri = 'tracker';        $this->perm = str_replace('_', '.', $this->uri);        //$subdomain = \Route::current()->parameter('subdomain');        $this->middleware('permission:'. $this->perm .'.create', ['only' => ['create', 'store']]);        $this->middleware('permission:'. $this->perm .'.create', ['only' => ['create', 'store']]);        $this->middleware('permission:'. $this->perm .'.read', ['only' => ['show']]);        $this->middleware('permission:'. $this->perm .'.update', ['only' => ['edit', 'update','activate', 'confirmActivate']]);        $this->middleware('permission:'. $this->perm .'.delete', ['only' => ['destroy', 'confirmDestroy']]);        $this->middleware("one.permission:{$this->perm}.create&{$this->perm}.read&{$this->perm}.update&{$this->perm}.delete",            ['only' => ['index']]);    }    /**     * Display a listing of the resource.     *     * @return \Illuminate\Http\Response     */    public function index(Request $request)    {        $q = null;        $uri = $this->uri;        $user = Auth::user();        $perm = $this->perm;        $title = trans_choice('app.' . $uri .
