Value cannot be null error in Sitecore powershall report download

Question

I am trying to generate report using powershell. I am getting results but when I tried to download report using powershell report dialog box throwing error as shown in below screenshot

Please see below code that I wrote to generate report, my Sitecore version is Sitecore 9 update 2 and powershell version is 4.7.2

$startPath = "master:/sitecore/content/Home"
Write-Host "Search started $(Get-Date -format 'u')"   
$linkProvider = [LM.Lightcore.Links.LinkProvider]::new()
$urlOptions = [Sitecore.Links.UrlOptions]::new();
$list = [System.Collections.ArrayList]@()

$itemsToProcess = Get-ChildItem $startPath -Language * -Recurse

if($itemsToProcess -ne $null) {

    $itemsToProcess | ForEach-Object { 
         $match = 0;
         foreach($field in $_.Fields) {
                 if($field -match '.*__SearchText*') {
                      $item = Get-Item ("web:" + $_.ID)
                     $info = [pscustomobject]@{
                         "FullPath"=$_.Paths.FullPath
                         "ItemUrl"=$linkProvider.GetItemUrl($item, $urlOptions)

                     }
                     [void]$list.Add($info)
             }
         }
     }

}

Write-Host "Search ended $(Get-Date -format 'u')"

Write-Host "Items found: $($list.Count)"

$list | Show-ListView  

Close-Window

Thanks Rishi

This comes due to the old version of PowerShell i.e. 4.7 which doesn't have proper support for pscustomobject. Either upgrade version to at least 5.1 or be specific when calling to show-listview i.e. give actual field name to show in report like show-listview -property FullPath, ItemUrl.

Hope it gives you an idea of the resolution.
