CSOM And FieldURLValue Error

I am trying to set a URL Field to update the Description and every time i run this ClientSide (via Powershell) I get the following error Exception calling "ExecuteQuery" with "0" argument(s): "Invalid URL: Microsoft.SharePoint.Client.FieldUrlValue

Basically what I'm trying to do is to set the URL to a Folder in a Document Library for a Specific User

The List will show

Users Name

Dept

Team

Document Library URL

Currently it shows it all correctly however its not that nice to see a huge URL in the Document Library URL field hence I want to Update it to show the Description which should show "User's Documents"

Easy done on Server Side and i have it Working on Server Side - However I would like to set this Client Side

So an example is

Ryan

IT

SharePoint

$url = $item["Document_x0020_Url"].url
        $ofldurl= new-object Microsoft.SharePoint.Client.FieldUrlValue
        $ofldurl.URL = $url
        $ofldurl.Description = $item["Title"]+"'s"+" "+"Documents"
        $item["Document_x0020_Url"] = $ofldurl
        $item.update()
        $context.ExecuteQuery()

I have double Checked and the URL is Set correctly in the Class (or at least it seems it to me) below is the output from the FieldURLValue Variable I had Created

Can Anyone see why this is not working at all or is this just me having a bad day?
