试图在现有的codeigniter应用程序中加载视图，需要关于我遇到的错误的建议

我刚刚开始开发一个代码点火器应用程序。

这个项目很简单，我只需要创建一个视图并从数据库中获取一些数据。

然而，当我尝试访问视图时，我总是会遇到这些错误。

我不知道这些错误是什么意思。

这是我用来在默认控制器类中加载视图的代码，它是一个独立于该类中索引函数的函数。

function watchlist(){
            $this->load->view("watchlist_view");
        }

以下是我在浏览器中访问视图的方式。

localhost/watchlist/index.php/home/watchlist

以下是我犯的错误。

        }
