Closest position on a Spline to a Player

Is this in the context of Spline movement only (requires a Spline)? Please confirm.

Because Im in UE4.27 and using [Simple Move to Node]. And the question sounds like a problem I have with Epic’s node: it only makes the edge of the Player’s capsule Move to the Loc, but not the center of the Capsule.
Thus if Cap radius = 30, then the Location has an error of 30 units (very annoying, and I cant use AI nodes on Player).
