We are using System Center Orchestrator 2012 with the vSphere Integration Pack. For reference, we are running vSphere 5. All of the runbook activities are working except the "Get VM List" activity. Any time we attempt to open the properties page or set the configuration, we receive the following error. 

Details: Object reference not set to an instance of an object.

Exception: IntegrationPackException

Has anyone else experienced this issue? I would like to know if there is a fix or workaround available. Thank you.
