Some Get Data node for PCG graphs does not work within actors

I placed the PCG as a component in the actor, but some nodes doesn’t work.

I tried to use landscape information with Get Landscape Data or Get Ray Hit Query, but nothing is displayed when I debug.However, if i place a PCG graph on its own, it will be displayed in debug.

So the node itself should be correct, but I think something is interfering with it because it’s placed on an actor.What could be the cause?

I looked at the tutorials, but they were all outdated versions and many elements had been removed, so they weren’t helpful.

Get Spline Data worked as expected, probably because it references a spline within an actor.
