Can't use node path mode for Get translation node in vs

[WindwithNothing]

Godot version: v3.2.2.stable.official

OS/device including version: GLES3

Issue description: I change Set Mode from Self to Node Path for Get translation, but it can't find selected node in running. It seems like only can get self translation.
And, I find my vs file can run in root object. When I set target is RigidBody it can get world position, but when I set target is position3D(1) it get relative position. I realize Get translation node is get position for parent.
I'm a beginner, I don't find a way to get world position for now. I don't know if the engine have this function. If it haven't, I hope it will add this function in future.
