将文件权限更新为“所有者”失败并出现 500 内部错误

Question

对于我们的域，需要将特定文件夹中的文件从一个用户传输到管理员帐户。管理员帐户对所有文件都具有“作者”角色。两个用户在同一个域中。

我使用域范围的委托作为授权方法。

将管理员帐户的权限从“writer”更新为“owner”时，程序返回 500 Internal Error。任何帮助将不胜感激。谢谢！

意识到我应该使用车主的电子邮件来获取驱动服务。这在更改那一行后起作用。谢谢。

    Drive userDriveService = getDriveService(ORIGINAL_OWNER_EMAIL);
