Client input to server

I put an actor on the floor, I can use client to collision it trigger server event(like first image) ,but I can’t use client input to trigger server event(like second image)

The weird thing is server can use input trigger server event,only client can’t

Do you enable the Input for a Player Controller? If yes, then you have the Problem, that if you use get Controller the index is 0. This is allways the Server.
For this i have my own flow that works with Server and Client.

I made it this way:
Overlapping actor->CastTo(your Player)->from that get Controller and->castTo(your Player Controller)->enable Input.

With this i only enable the Input for the owning pawn. I am not sure if this above is right. I am not on my Computer. If you want i can post a screenshot from my Project.

I use this, is that right?
If you post a screenshot,I will be very happy
