Multiplayer Possession Mechanic (Not working on clients)

I’m trying to make multiplayer game (for two players for the first time).

And I’ve got mechanic:

Every player can possess every creature - when you watch at creature and press R, Player character starts to fly to creature and possess creature at the end of the flight (Player character pawn hidden inside creature’s body without collision)

And it works perfectly in singleplayer, but not in multiplayer (On clients)

Only thing that I understood that problem in target (cause we possess with index) but other nodes (below “Get player controller”) don’t work too

Is there way to get actual player controller index into runtime? (if problem in this, cause I’m not sure)
