How to solve this? Skript-Reflect

[The_SrMega]

Hello, I am trying to use the lunar api with skript reflect to activate the staff modules, but, when trying to activate them I get the following error in the console: https://prnt.sc/1wg247a (The server version is Paper 1.12.2)
This is my code:

import:
    com.lunarclient.bukkitapi.LunarClientAPI
command /staffmodules:
    permission: staff.lunarmodules
    trigger:
        LunarClientAPI.giveAllStaffModules(player)

player outputs the player's name, java needs another format - not sure which one tho

Ok, but, how i can parse it as org.bukkit.entity.Player
