Communication between Level Blueprint a client BP : No owning connection for actor

Hello,

In a Local multiplayer project, I try to make a connection between a level Blueprint (form persistent level) and a client pawn (the project on I’m working on is make like that…). Indeed, I’m trying to execute a function “Run On Server” (on The Level Blueprint) from client’s Pwan BP. So I used an Event Dispatcher, but when the “Run on Server” function is called, a** ProcessRemoteFunction: No owning connection for actor L_Main** (name of the persistent level) appears.

I try using Blueprint Interface, but same results.

A current and probably simple error, but I cannot solve the logic. Anyone got an idea ?

Thanks !
