SharePoint Online PowerShell problem: Cannot convert the `Microsoft.SharePoint.Client.ClientContext` | José Quinto

Introduction

When we are doing a SharePoint deployment using PowerShell there we could find similar problem like that:

Cannot convert the “Microsoft.SharePoint.Client.ClientContext” value of type “Microsoft.SharePoint.Client.ClientContext” to type “Microsoft.SharePoint.Client.ClientRuntimeContext”.”

Problem

In my scenario I was trying to Activate a Sandboxed solution using PowerShell:

$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl);
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($adminUsername, $secureAdminPassword);
$ctx.Credentials = $credentials

[Microsoft.SharePoint.Client.Publishing.DesignPackage]::Install($ctx, $ctx.Site, $wsp, $filerelativeurl);

And I received the error mentioned before. I did some checks:

• Run as administrator
• Run using SharePoint Online PowerShell command line.
• Check I have installed Client Components.

Solution

But after some investigations, the reason is the version of SharePoint Client Components and SharePoint Online Management Shell I was using.

To solve it, Install latest version of them, uninstall previous versions and restart Powershell console.
