regex - 为什么 New-AzureRmVM 给出实体名称错误？

Question

当我从 PowerShell ISE 运行此代码时

New-AzureRmVM -ResourceGroupName $ResourceGroupName -Location $Location -VM $VM

我收到此错误

New-AzureRmVM : The entity name is invalid according to its validation rule: ^[^_\W][\w-._]{0,79}(?<![-.])$.
StatusCode: 400
ReasonPhrase: Bad Request
OperationID : 'my-operation-id'
At line:1 char:1
+ New-AzureRmVM -ResourceGroupName $ResourceGroupName -Location $Location -VM $VM
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [New-AzureRmVM], ComputeCloudException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.Compute.NewAzureVMCommand

$ResourceGroupName 包含我的资源组名称，本例中为“foobar.com”。

$Location 包含“East US 2”。

$VM 包含下面我的虚拟机配置

ResourceGroupName        :

谁能告诉我它所指的实体名称是什么？是虚拟机的名称、存储位置之一的名称等吗？ 据我所知，一切都与正则表达式匹配，所以我不明白为什么会收到此错误。谷歌搜索命令名称只显示了一些结果，根本没有提及任何有关实体名称的内容。

没关系，我是通过反复试验才弄清楚的。数据和操作系统磁盘的名称中显然不能有空格。如果 Azure PS 模块有更好的文档记录，将会有所帮助。
