Invoke-SCCMScript: Generic Error

[bryandam]

Josh, wondering if you remember where you discovered the XML parameter format you're using for InnerParametersXML in this script?

I've been using this for sometime and at some point recently it's stopped working with the WMI method call just returning 'Generic Error'. I can't find that XML (<ScriptParameter ParameterGroupGuid .... />) anywhere and that's my best guess as to what's changed.
