在PHP8.2中，我有下面结构来实现CRUD基础

基础请求

use Illuminate\Foundation\Http\FormRequest;

class BaseRequest extends FormRequest
{
}

基础控制器

<php?>
abstract class CRUDBaseController extends BaseController
{
 public function update(BaseRequest $request,$id)
 {
    $this->authorize('update', $this->service->getModel());
    $this->service->update($id, $request->validated());
    return redirect()->route($this->getViewPath() . '.index');
 }
}

用户请求

class UserRequest extends BaseRequest 
{
}

然后UserController从CRUDBaseController扩展并覆盖一些父方法，如update方法

class UserController extends CRUDBaseController
{    
      
     public function update(UserRequest $request, $id)
     {
         return parent::update($request,$id);
     }
 }

虽然UserRequest继承自BaseRequest，但为什么在调用此方法时会出现以下错误？为什么我得到这个错误时，这些对象相同的父？
In UserController.php line 27: Declaration of App\Http\Controllers\API\UserController::update($id, App\Http\Requests\UserRequest $request) must be compatible with App\Http\Controllers\CRUDBaseController::update($id, App\Http\Requests\BaseRequest $request)
