I have a script where I locate a document library and try to add a folder to it, however, it fails. This is my current failing script:
$web = Get-SPWeb($completeUrl)
$DocumentLibrary = $completeUrl + "/DocumentLibrary"
$site = New-Object Microsoft.SharePoint.SPSite($DocumentLibrary)
$website = $site.OpenWeb()
$list = $website.GetList($DocumentLibrary)
$newFolder = $list.AddItem("", [Microsoft.SharePoint.SPFileSystemObjectType]::Folder)
$newFolder["Title"] = "Weekly"
$newFolder.Update()
The exception that I get is: Exception calling "Update" with "0" argument(s): "Invalid item data -- missing FileRef."
Any hints?
