Question

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.

Script:

$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

Error:

Exception calling "Invoke" with "1" argument(s): "Element 'Objs' with namespace name 'http://schemas.microsoft.com/powershell/2004/04' was not found. Line 3, position 2."

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).

To get the SPE version you can run the following command from within the SPE Console or ISE: $PSVersionTable

To get the SPE Remoting version you can run the following command from with the Windows PowerShell Console or ISE: Get-Module -Name SPE
