"No shared parameter file found" - Orchid Package

New to shared parameter.

When I ran either Add shared parameter or Create shared parameter in Parameter.dyn that come with Orchid samples, I got “No shared parameter file found” message

How to solve the problem?
Parameter.dyn (83.2 KB)

Have you specified a shared parameters file within Revit? (not in Dynamo). Orchid is probably looking for the shared parameters file loaded into Revit, but can’t find one.
