使用RegistryManager.ApplyConfigurationContentOnDeviceAsync进行部署-格式错误的内容

问题描述

我正在构建一个工具，该工具可用于基于CMDB中的配置集或属性将模块部署到IoTEdge。

该工具能够生成部署清单，并且正在使用.NET SDK-特别是-RegistryManager.ApplyConfigurationContentOnDeviceAsync来应用部署。

ConfigurationContent中的序列化字符串如下。应用此模板后，SDK中没有错误，但是在Edge的门户中，其状态显示为400-部署配置格式错误或无效。

使用VSCode中的“单设备”部署来应用时，相同的模板（只是ModulesContent）可以正常工作。因此，不确定是什么原因导致模板部署无法通过RegistryManager失败。无法找出模板中格式错误的内容。感谢任何指导。

解决方法

我不完全知道区别以及为什么会起作用。我有一个可以成功部署的工具版本。我正在使用Newtonsoft进行JSON解析。我已经在CSharp SDK中切换到System.Text.Json，这似乎已将JSON分解为格式错误的状态。我切换回Newtonsoft，部署很好。
