Create multiple folders on all site collection sites

[Ximo]

Hi,

I am trying to add a series of folders to all the sites on a site collection with the below script:

#Config Variables
$SiteURL = "https://somesite.sharepoint.com/sites/pwa"
$CSVFilePath = "C:\Folders.csv"
$LibraryName = "Project Documents"
 
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Interactive
$SubSites = Get-PnPSubWeb -Recurse

        ForEach($Site in $Subsites) 
        {   
            #Get the CSV file
            $CSVFile = Import-Csv $CSVFilePath

            #Read CSV file and create folders
            ForEach($Row in $CSVFile)
            {
                $FolderName = $Row.FolderName

                #Create Folder
                Add-PnPFolder -Name $Row.FolderName -Folder $LibraryName
                Write-host "Ensured Folder:"$FolderName -f Green

            }
        }

But the output is always the same:

Add-PnPFolder : File Not Found.
At C:\Users\user\Desktop\Add folders to all sites.ps1:21 char:17
+ ...              Add-PnPFolder -Name $Row.FolderName -Folder $LibraryName
+                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : WriteError: (:) [Add-PnPFolder], ServerException
    + FullyQualifiedErrorId : EXCEPTION,PnP.PowerShell.Commands.Files.AddFolder

Does anybody see where the problem is?

Thank you in advance
