The “Script Control” reflection tasks (Execute Function, Get/Set Property etc), at least right now, only work with Component derived types, because the Tasks themselves also only work with Component derived types for the agent. This is something that has been requested before though, so it is quite high on my roadmap to implement/change.
Where did you find the [NodeCanvasPreferredType] attribute by the way? Such an attribute does not exist in NodeCanvas :).
