FPS C++ Tutorial: Where did GetMovementMode node go? And how can I work around it?

Very succinctly, in the c++ tutorial for building an fps, it asks, during the setup of the state machine driving the arm animations, to use a GetMovementMode node in the blueprint event graph. However, casting from both Try Get Pawn and GetPlayerController results in a NULL so there’s nothing to get the the movement mode from. I searched through the docs in hopes of an answer but nothing really makes sense. There’s a movementmode as part of the Skeletal Mesh (if I recall correctly) but this isn’t the same as in the tutorial.

Is this part of the persona changes to character animation? Am I missing something brutally obvious?
