Laravel文件管理器无法上传共享文件夹中的文件

Question

我正在使用CKEditor，现在正尝试将其与UniSharp文件管理器集成。我可以在共享文件夹中创建文件夹，但是当我尝试上传文件时，出现此错误：您必须选择一个文件！ https://imgur.com/a / 2vLNUNz。

我的lfm.php文件：

我已经检查了文件权限，并将它们设置为777。
我已经安装了exeif扩展名和ImageMagick。这是我的phpinfo屏幕截图https://imgur.com/By8O3iz。
我是Laravel的新手，所以这可能是一个明显的错误，但是经过几天的搜索，我看不到它。

感谢您的时间！
