google-drive-api - 如果文件已共享到组并且组已删除，则无法检索权限

Question

我在使用 Google Drive API 时遇到问题。如果您将文档共享给群组，则该群组将被删除，文件的权限将无法再提取。

重现步骤。
1.通过UI在驱动中创建文档
2. 将文档共享到谷歌内部组
3.通过cPanel删除群组。
4.尝试使用drive api拉取文件权限。

语言:Java驱动 API : v2
打电话:

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;  
}  
}  
}  

错误信息:

Answer 1

我在使用 python 库时看到了同样的行为，当“未知组”出现在权限列表中时，我收到 500 错误。
