阿祖勒姆-地形不像预期的那样

Question

我正在尝试创建一个Terraform项目，以创建Azure订阅中所需的一切，因此资源组、vnet、子网和VM。

但是，当我运行这一次并再次尝试时，它声明它不能删除正在使用的子网。我没有更改任何关于子网或连接到它的VM的任何内容。

错误:创建/更新虚拟网络：(名称为“/ resources”)：network.VirtualNetworksClient#CreateOrUpdate:失败发送请求: StatusCode=400 --原始错误: Code="InUseSubnetCannotBeDeleted“Message=子网构建代理正在被StatusCode=400使用，不能被删除。为了删除子网，删除子网中的所有资源。参见aka.ms/deletesubnet。Details=[]

任何帮助，为什么它是这样的行为，或一个解决办法，将不胜感激！

结果发现，不能将vnet块中的嵌套子网与显式定义的azurerm_subnet混合在一起。
