Using a script to bulk create folders in SharePoint using the Resolve-PnPFolder cmd and trying to also update a specific column for the new folders.

The CSV has two columns: FoplderSiteRelativeURL and RDO (RDO is what I’m trying to update)

#Config Variables
$SiteURL = "https://xxxxxxxxxx.sharepoint.com/teams/GroupName"
$CSVFilePath = "C:TempFolders.csv"
  
Try {
    #Connect to PnP Online
    Connect-PnPOnline -Url $SiteURL -Interactive
 
    #Get the CSV file
    $CSVFile = Import-Csv $CSVFilePath
   
    #Read CSV file and create folders
    ForEach($Row in $CSVFile)
    { 
        #Create Folder if it doesn't exist
        $newfolder = Resolve-PnPFolder -SiteRelativePath $Row.FolderSiteRelativeURL | Out-Null
        $newfolderid = Get-PnPListItem -list Documents -id $newfolder.id
        Set-PnPListItem -list Documents -identity $newfolderid.id -values @{"RDO" = $row.RDO}
        Write-host "Ensured Folder:"$Row.FolderSiteRelativeURL -f Green
    }
}
catch {
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}

The above code gives me the following error:
Error: Cannot bind parameter ‘Id’ to the target. Exception setting “Id”: “Cannot convert null to type “System.Int32″.”
