Sync-UDElement not working. Basic example

Universal Dashboard
1

Does this work for anyone? I’m using v2.9.0 and Websockets is installed. Server is Windows Server 2016.

 Start-UDDashboard -Port 1005 -force -Dashboard (
    New-UDDashboard -Title "Hello, IIS" -Content {

        Enable-UDLogging -Level Debug -FilePath C:\Temp\log.txt

        New-UDCard -Title "Hello, IIS"

        New-UDElement -Id "SyncMe" -Tag span -Endpoint {
            New-UDHtml -Markup (Get-Random)
        }

        New-UDButton -Text "Update" -OnClick {
            Sync-UDElement -Id "SyncMe" -Broadcast
        } 
     }
  )

Here is the log from when I click on the button.

Hi,
If you’re using IIS you’ll need the -wait param, also make sure you’ve followed all the documentation here:
https://docs.universaldashboard.io/webserver/running-dashboards/iis

Although saying that I’d expect you to get errors before that point if anything wasnt right with websockets etc.
