AWS Amplify GraphQL 中突然未定义字段“所有者”

Question

今天我尝试在我的 AWS GraphQL 架构的“用户”类型中添加一个“名称”字段。 运行“放大推送”和“代码生成”后，我收到来自 AWS 的错误消息，说“所有者”是 null。 在并排比较了我的 git 历史记录后，我发现 codegen 在我的查询中删除了自动生成的所有者字段，同时添加了两个新字段“createdAt”和“updatedAt”。 不确定如何/为什么会发生这种情况，我恢复到早期的 git 提交，其中一切工作正常并被推动放大。 我所有的文件都恢复到一切正常的提交。 但是，我仍然收到“所有者”是 null 的错误。 GraphQL 架构和终端截图如下。 如果有帮助，很乐意提供其他文件（查询、突变等）。

坏消息：您从数据库中删除了这些字段。 所有者数据消失了，这就是为什么它回来 NULL 现在您将其重新添加到架构中。
