Having trouble uploading sub folders to Sharepoint online using PowerShell

Question

Hi there,
I have been attempting to upload folders and files to a document library on Sharepoint Online. I can upload the top-level folder and the files in that folder but when i comes to the sub folders i get this message: 
New-Object : Exception calling ".ctor" with "2" argument(s): "Access to the path 
'C:\FilePath\TestFolder\TestFolder1' is denied."
At C:\FilePath\ImportFiles_Test1.ps1:54 char:29
+               $FileStream = New-Object IO.FileStream($File.FullName,[System.IO.F ...
+                             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [New-Object], MethodInvocationException
    + FullyQualifiedErrorId : ConstructorInvokedThrowException,Microsoft.PowerShell.Commands.NewObjectCommand
I'm running as an Administrator so I have full access to the folders
here's my code so far
#Specify tenant admin and site URL
$User = "[email protected]"
$SiteURL = "https://company.sharepoint.com/sites/TestSite"
$Folder = "C:\Users\user\Documents\SharepointTestFolder"
$DocLibName = "Admin"
#Add references to SharePoint client assemblies and authenticate to Office 365 site - required for CSOM
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
$Password = Read-Host -Prompt "Please enter your password" -AsSecureString
#Bind to site collection
$Context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($User,$Password)
$Context.Credentials = $Creds
#Retrieve list
$List = $Context.Web.Lists.GetByTitle($DocLibName)
$Context.Load($List)
$Context.ExecuteQuery()
Function ImportFiles()
#Get name of folder
$NewFolder = Split-Path $Folder -Leaf
#upload folder to sharepoint
$UploadFolder = $List.RootFolder.Folders.Add($NewFolder) #this may not upload folders within folders.
$Context.Load($UploadFolder)
$Context.ExecuteQuery()
$FilesInFolder = Get-ChildItem $Folder | ? {$_.PsIsContainer -eq $False}
#Loop Through Folder
Foreach ($File in (dir $Folder))
#If file
If($File)
#Upload file to Sharepoint
$FileStream = New-Object IO.FileStream($File.FullName,[System.IO.FileMode]::Open)
$FileCreationInfo = New-Object Microsoft.SharePoint.Client.FileCreationInformation
$FileCreationInfo.Overwrite = $true
$FileCreationInfo.ContentStream = $FileStream
$FileCreationInfo.URL = $File
$Upload = $UploadFolder.Files.Add($FileCreationInfo)
$Context.Load($Upload)
$Context.ExecuteQuery()
Else
recurse ImportFiles
ImportFiles
If anyone could help me I'd be so grateful!!
Thanks!!

Answer 1

The exception is pretty clear. for some reason the script is not able to open the folder TestFolder1 on the local hard drive.
I noticed in the script you have specified the $Folder variable to be "C:\Users\user\Documents\SharepointTestFolder" while the exception is for "C:\FilePath\TestFolder\TestFolder1"
Will you please help me understand this difference?
Also, sorry I'm not familiar with the "recurse" calling method. I'm suspecting you're telling it to call the ImportFiles() function again, though if this is the case it looks to me that it's reusing the same $Folder variable that was defined at the start,
rather than using the folder object you have just identified.
