Google drive api 如果文件已共享给组且组已删除，则无法检索权限

我对Google Drive api有问题。如果将文档共享给组，则该组将被删除，文件的权限将无法再提取

复制的步骤。
1.在直通式UI中创建文档
2.将文档共享给google内部组
3.通过cPanel删除组。
4.尝试使用驱动器api获取文件的权限

语言：Java 驱动器API:v2
电话：

public static void retrievePermissions(Drive serv, ArrayList<Permission> perms, String userEmail, String fileId, String title) throws Exception {  

PermissionList permissions = null;  
int retry = 5;  

while (retry > 0) { 
   try {  
       permissions = serv.permissions().list(fileId).execute();  
       perms.addAll(permissions.getItems());  
       retry = 0;  
   }catch(com.google.api.client.googleapis.json.GoogleJsonResponseException je){  
       je.printStackTrace();  
       System.err.println("JSON EXCEPTION DOC TITLE :: " + title + " :: user " + userEmail);  
       retry = 0;  
} catch (Exception e) {  
       retry = retryError(e, retry, printStackTrace);  
       if (retry == 0)  
       throw e;  
}  
}  
}

我使用python库看到了同样的行为，因为“未知组”出现在权限列表中，我得到了500个错误回复。

感谢您的报告。这看起来确实像个虫子。我会试着复制，然后再给你回复。我不能复制这个。我正常获得权限列表，包括组的权限。删除组后是否需要等待一段时间？我也尝试了内部组和外部组。我不确定这是否只影响了旧文档，我想我可以复制它。我在测试大量的文档，当组转到UI中的“未知组”时，就是发生这种情况的时候。我也可以给你一些文件Id。如果您愿意，我可以在我的开发域中为您创建一个帐户，这样您就可以提取这些文档。我可以PM你的信息，如果你可以看看。只是看了我的最后一次测试。删除组时，必须花费一些时间才能传播到文档。我昨天创建的测试现在正在生成异常。你能再试一次吗。
