无法在JSON中正确输出数组

Question

我正在从CSV文件中读取内容，并尝试创建类似于以下内容的JSON结构，connections属性是从3列组合而成的（即在线，镜像和共享），我将它们组合成一个数组作为JSON中的连接。我不知道为什么我没有使用数组获得正确的属性格式。

{
  "connectionmap": [
    {
      "Environment": "abc",
      "connections": ["x1", "x2", "x3"]
    },
    {
      "Environment": "def",
      "connections": ["y1"]
    }
  ]
}

当前，我的代码是这样：

function connectionPointsGenerator {
    Param(
        [Parameter(Mandatory = $true)]
        [string]$CsvPath,
        [Parameter(Mandatory = $true)]
        [string]$OutPath
    )

    $Json = Import-Csv $CsvPath | ConvertTo-Json
    $JsonObject = $Json | ConvertFrom-Json 
    foreach ($env in $JsonObject) {
        [array]$connections = @()
        $connections += "$($env.online)"
        if ($env.mirror) {
            $connections += "$($env.mirror)"
        }
        if ($env.shared) {
            $connections += "$($env.shared)"
        }
        Write-Output "$($connections.GetType())"
        $env.PSObject.Properties.Remove("online")
        $env.PSObject.Properties.Remove("mirror")
        $env.PSObject.Properties.Remove("shared")
        $env | Add-Member -MemberType NoteProperty -Name "connections" -Value $connections -PassThru | Out-Null
    }
    $hash = @{}
    $hash.Add("connectionmap",$JsonObject)
    $hash.connectionPointMapping.dit
    $FinalJson = $hash | ConvertTo-Json | Out-File $OutPath
}

这就是我得到的：

{
  "connectionmap":  [
    {
      "Environment":  "abc",
      "connections":  "x1 x2 x3"
    },
    {
      "Environment":  "def",
      "connections":  "y1"
    }
  ]
}
