启动关闭超过 1 个月的虚拟机后，IoT Edge 运行时错误 400

如何解决启动关闭超过 1 个月的虚拟机后，IoT Edge 运行时错误 400

我有一个在 Ubuntu 16.04 上运行 IoT Edge 1.0.10.3 的工作虚拟机，我在过去一个月左右关闭了它。

今天打开它发现：

• 我可以正常启动所有模块。他们都报告正在运行
• 运行时响应为：400 -- The deployment configuration is malformed or invalid
• 运行 iotedge 检查，似乎没有任何错误
• 当我尝试 set modules 时，在 IoT 边缘模块下：There are no listed IoT Edge Modules
• 我还在 EdgeHub 日志中收到以下错误：

在过去一个月的离线状态下会发生什么使边缘进入不一致状态？

解决方法

根据 docs，您的日志引用的 $schemaVersion 是在 1.0.10 中引入的。文档说推荐使用该属性，但似乎运行时需要它。在您的评论中，您包含了缺少 $schemaVersion 的所需属性。尝试设置以下所需的属性：

"properties":{
  "desired":{
     "routes":{},"schemaVersion": "1.1","$metadata":{
        "$lastUpdated":"2020-11-25T18:26:39.4780665Z","$lastUpdatedVersion":5,"routes":{
           "$lastUpdated":"2020-11-25T15:03:42.6671499Z","$lastUpdatedVersion":4
        }
     }
  }
}
