json - VMWare对象上的ConvertTo-Json不起作用

Question

在powershell中，将VM对象转换为json时，
($ json = ConvertTo-Json $ vm -Compress)

我收到“具有相同键的项目已添加”异常。

getVMHosts函数返回VM guest虚拟机的列表。请在下面找到我的代码。

function getVMHosts{
Param(
[Parameter(Mandatory=$True,Position=1)]
[string]$vcenter,
[Parameter(Mandatory=$False)]
[switch]$info=$false
)
try
{
    Write-Verbose "$(get-date -Format "dd/MM/yyyy HH:mm") - Function:$($MyInvocation.MyCommand) - Importing VMWare modules" -verbose:$info
    Get-Module -ListAvailable -Name "VMware.*" | Import-Module
    Write-Verbose "$(get-date -Format "dd/MM/yyyy HH:mm") - Function:$($MyInvocation.MyCommand) - Connecting to Vcenter:$vcenter" -verbose:$info

    Write-Verbose "$(get-date -Format "dd/MM/yyyy HH:mm") - Function:$($MyInvocation.MyCommand) - Getting Data center servers" -verbose:$info
    $DCs = Get-Datacenter
    $VMs = $null
    foreach($dc in $DCs)
    {
        Write-Verbose "$(get-date -Format "dd/MM/yyyy HH:mm") - Function:$($MyInvocation.MyCommand) - Getting VM servers for Data Center:$dc" -verbose:$info
        $VMs=$VMs+ $(Get-Datacenter -Name $dc.Name | Get-VM -Verbose:$info| Select PowerState,Name, NumCpu,MemoryMB,GuestId,VMHost, @{N="IP Address";E={@($_.guest.IPAddress[0])}})
    }

    return $VMs
}
catch
{
    $errorMessage = "$($_.Exception.Message)`n$(($_|select -ExpandProperty invocationinfo).PositionMessage)"
    Write-Warning -Message "Catched an exception in Function:$($MyInvocation.MyCommand)`n$errorMessage" -Verbose:$true
}
}
$vmHosts = getVMHosts -vcenter "vcenter"
$counter = 0
foreach($vm in $vmHosts)
{    
if($vm -ne $null){$json = ConvertTo-Json $vm -Compress;insertToElasticSearch json $json -info:$true -Verbose:$true}   
}

尝试ConvertTo-JSON -Depth 1。 Sounds like对象中具有相同名称的属性。
