Python 数据存储中的属性用户已损坏：

您好，我收到一条奇怪的错误消息：

属性用户在数据存储中已损坏

你能告诉我这是什么意思吗？我该怎么办？这是完整的追踪

尝试通过数据存储查看器加载有问题的实体，以查看用户字段中实际存储的内容。
这是应用程序引擎数据存储的已知问题。它与您的代码或应用程序无关

App Engine团队正在进行修复，在您等待时，此处发布了一个解决方案：
它可能已损坏-类型与数据一起存储，而不是单独存储在模型定义中，因此模型中的更改将导致不同的错误。不过，将其加载到管理控制台是一个有用的测试。谢谢！我理解我们的怀疑某个特定实体中存在损坏。当试图通过管理控制台访问它时，GQL将无法工作。我将再次尝试，看看是否可以找到损坏。我遇到了相同的问题。谷歌似乎与第三方openid提供商有一些问题。

。使用谷歌自己的联合登录服务，一切都很好。认识Andrey很有趣。谢谢你的评论。
