Google Drive API/SDK，使用服务帐户更改所有者失败

Question

我尝试使用google drive api v2以编程方式更新google drive中一些文件的所有者权限。（就像google Admin Console在“drive/Transfer Hownership”表单上所做的那样）我创建了一个服务帐户，并使用它的ID和超级管理帐户来创建凭据和“DriveService”对象。我可以列出所有与我共享的文件，并枚举“文件”的“所有者”集合。向文件添加一个新权限(role=“writer”）很好。如果我试图将新权限更改为role=“owner”，我会得到一个内部错误500。

以前有人见过这个错误吗？我该如何处理？
