谷歌驱动PHP权限

我想在谷歌驱动器上的一些文件夹上共享权限，帮助谷歌服务帐户，但致命错误:未捕获的异常'Google_Service_Exception'与消息'错误调用POST https://www.googleapis.com/drive/v2/files/0ByXNGBI2AHyZX0RZd2pROE5qNFk/permissions:(500)内部错误'它的问题只在使用服务帐户类型身份验证时出现

当我粘贴更多的范围array('https://www.googleapis.com/auth/drive','https://www.googleapis.com/auth/drive.file'),时，我收到404错误文件未找到0ByXNGBI2AHyZX0RZd2pROE5qNFk
