Upload a file to Sharepoint

[gijsbert]

I wrote a powershell script to upload a file to sharepoint online.
The script works fine in PowerShell ISE, but throws an error when used in a powershell studio form. Can some one help me figure this out?

$FileStream = New-Object IO.FileStream($SourceFile.FullName, [System.IO.FileMode]::Open)
$FileCreationInfo = New-Object Microsoft.SharePoint.Client.FileCreationInformation
$FileCreationInfo.Overwrite = $true
$FileCreationInfo.ContentStream = $FileStream
$FileCreationInfo.URL = $File
$Upload = $List.RootFolder.Files.Add($FileCreationInfo)
$Context.Load($Upload)
$Context.ExecuteQuery()

throws error:
ERROR: Exception calling "Add" with "1" argument(s): "The 'parameters.Url' argument is invalid."

The error tells you what the problem is. The "$file" argument is invalid.

Probably works in the ISE because $File is contaminated from
something else but not initialized in the script.
