I want to select points with the mouse in SceneWidget, but pick_interactor = std::make_shared<PickPointsInteractor>(*scene_widget, *camera );always wrong.This is my graduation project，help please!

scene->SetFrame(gui::Rect(panel_width, 0, this->GetSize().width - panel_width, this->GetSize().height));
panel->SetFrame(gui::Rect(0, 0, panel_width, this->GetSize().height));

    SceneWidget* scene_widget = scene.get();  
    std::shared_ptr<Open3DScene> scene_ptr = scene_widget->GetScene();
    Open3DScene* open3d_scene = scene_ptr.get();
    Camera* camera = open3d_scene->GetCamera();
    pick_interactor = std::make_shared<PickPointsInteractor>(         //An error will be reported here
        *scene_widget, 
        *camera
    );
