Trying to update a column for a number of folders in SharePoint online. I have a CSV with the Item ID and the update for the column. Here is the code:

#Config Variables
$SiteURL = "https://xxxxxxxxxxx.sharepoint.com/teams/TestSite"
$DestinationFolderIds = Import-Csv -Path "C:TempFile2.csv"
  
#Connect to PnP Online
Import-Module PnP.PowerShell
Connect-ExchangeOnline
Connect-PnPOnline -Url $SiteUrl -Interactive
   
#Update Folders
ForEach($DestinationFolderID in $DestinationFolderIds)
{ 

    $folderid = Get-PnPListItem -List "Documents" -Id $DestinationFolderID.folderid 
    Set-PnPListItem -list Documents -identity $folderid -values @{"RDO" = "$DestinationFolderID.rdo"} | Out-Null
}

Getting this error:

Cannot bind parameter 'Id' to the target. Exception setting "Id": "Cannot convert null to type "System.Int32"."
