I'm trying to install and update package through powershell, below is the script. session is successfully created, but when invoking a remote script, I'm getting an error.


$file = "C:\inetpub\wwwroot\Test\Data\SitecorePackageDeployer\SampleTDSProject.update"
$session = New-ScriptSession -Username prem -Password **** -ConnectionUri http://test
$scriptBlock = [scriptblock]::Create("Start-ScriptSession -ScriptBlock {Install-UpdatePackage -Path $file -UpgradeAction Upgrade -InstallMode Update ; Start-Sleep -Seconds 10; [PSCustomObject]@{'IsComplete'=$true}}")
$job = Invoke-RemoteScript -Session $session -ScriptBlock $scriptBlock

  • My fix was to downgrade to Sitecore SPE 5.0. I Hope it will be fixet asap – JonasVeng Jul 17 '19 at 8:39
  • Can you provide the details of which version of SPE and SPE Remoting packages you used? – Michael West Jul 17 '19 at 19:39

The issue is most likely related to the fact you are using incompatible versions of the SPE Remoting package and SPE.

  • If you are using SPE 5.1 then you should be using SPE Remoting 5.1.
  • If you are using SPE 5.0 then you should be using SPE Remoting 5.0 (or 5.0.1).
