Powershell 变量不会迭代，值为空

以下代码生成一个列表：

    $users = Get-AzAksCluster -ResourceGroupName $resource_group -SubscriptionId $subscription_id |
Select-Object -Property DnsPrefix, KubernetesVersion, Location, Name, ResourceGroupName, @{e = { $_.Tags.creator | ConvertTo-Json | ConvertFrom-Json }; l = 'Tags' } |
Sort-Object -Descending Creator |
ForEach-Object {
    new-object psobject -Property @{
        AzurePortalFQDN         = $_.AzurePortalFQDN
        DnsPrefix               = $_.DnsPrefix
        Fqdn                    = $_.Fqdn
        Id                      = $_.Id
        KubernetesVersion       = $_.KubernetesVersion
        Location                = $_.Location
        Name                    = $_.Name
        NodeResourceGroup       = $_.NodeResourceGroup
        ProvisioningState       = $_.ProvisioningState
        ResourceGroupName       = $_.ResourceGroupName
        ServicePrincipalProfile = $_.ServicePrincipalProfile
        Creator                 = if ($_.Tags) { $_.Tags } else { "zNo Creator Found" }
    }
} |
Select-Object -Property Creator |
Where-Object {$_.Creator -ne "zNo Creator Found"} |
Format-Table -HideTableHeaders

当我尝试遍历列表时，foreach 中的 $users 变量为空，并且 $user 永远不会被填充

    foreach ($user in $users) {
    Write-Output $user
    $Output = Get-AzAksCluster -ResourceGroupName $resource_group -SubscriptionId $subscription_id |
    Select-Object -Property DnsPrefix, KubernetesVersion, Location, Name, ResourceGroupName, @{e = { $_.Tags.creator | ConvertTo-Json | ConvertFrom-Json }; l = 'Tags' } |
    Where-Object -FilterScript {$_.Tags.creator  -like $user} |
    Sort-Object -Descending Creator |
    ForEach-Object {
        new-object psobject -Property @{
            AzurePortalFQDN         = $_.AzurePortalFQDN
            DnsPrefix               = $_.DnsPrefix
            Fqdn                    = $_.Fqdn
            Id                      = $_.Id
            KubernetesVersion       = $_.KubernetesVersion
            Location                = $_.Location
            Name                    = $_.Name
            NodeResourceGroup       = $_.NodeResourceGroup
            ProvisioningState       = $_.ProvisioningState
            ResourceGroupName       = $_.ResourceGroupName
            ServicePrincipalProfile = $_.ServicePrincipalProfile
            Creator                 = if ($_.Tags) { $_.Tags } else { "zNo Creator Found" }
        }
    }

    Write-Output $Output

有人能指出为什么我可以写入输出 $users 并看到用户，但 foreach 无法对其进行迭代吗？

答案来自杰夫米尔纳是正确的。删除后Format-Table问题解决了。
