环境信息 细节 描述错误 DataStoreStateError：尝试在 DataStore “停止”时执行 DataStore.query()。 这只能在 DataStore “启动”或“停止”时完成。补救措施： 确保首先完成对 stop() 和 clear() 的所有调用。 如果这不是可能...
嗨，我有一个放大项目来托管 react-native 移动应用程序的后端。突然它停止工作了。任何对数据存储的调用都会收到我上面提到的消息。
我们的工作计划是提供放大后端作为 NPM 包。应用程序开发人员使用此程序包调用 AWS-Amplify。自 6 个月以来，一切正常，直到 4 天。我们没有重大变化或其他东西。刚刚添加了一些我认为不会导致此问题的 lambda 函数。
当应用程序打开时，我们正在启动数据存储。 DataStore.start() 并在 SignIng 事件和 SignOut 事件中清除它。很长一段时间（4 个月）以来，我们没有对此流程进行任何更改。
我们试图在本地重现该问题，但以某种方式不可能。因为我们使用 typescript 来编写我们的 NPM 包。我们使用 node 或 tsx 在本地测试功能，一切正常，然后我们将其发布并下载到另一个项目 react-native 中，一切正常。部署后，无法执行来自 DataStore 的任何操作。应用程序崩溃了，Sentry 向我们显示了上面的消息。 4 天前到现在又开始发生这种情况。
预期行为 能够执行数据存储操作功能（查询、保存、删除...等）/获取与数据存储的连接。
复制步骤 每当我们在 react-native 应用程序中调用数据存储功能时。它将显示此消息：
DataStoreStateError：尝试在 DataStore “停止”时执行 DataStore.query()。 这只能在 DataStore “启动”或“停止”时完成。补救措施： 确保首先完成对 stop() 和 clear() 的所有调用。 如果这不是可能...
