onResourceStart problem

[Hero192]

Hey guys im making a login system but i stuck on something, i want when i start the resource only people who have no account or they're guest account they who can see the gui ,since the onResourceStart event do not accept 'source' i tried this way but nothing works..

i did trigger from client to server it's for the GUI Visiblity

Here's the code, no error it just doesn't works

addEventHandler( "onResourceStart", root, 
function () 
    checkGuestAccount() 
end)  
  
function checkGuestAccount () 
    local account = getPlayerAccount(source) 
    if not account or isGuestAccount(account) then 
    showPlayerHudComponent ( source, "clock", true ) 
    showPlayerHudComponent ( source, "radar", true ) 
    showPlayerHudComponent ( source, "area_name", true ) 
    showChat ( source, true ) 
    showCursor( source, true ) 
    fadeCamera( source, true, 1 ) 
    setCameraMatrix(source, -1212.281, 185.058, 84.00, -1780, 790, 70)  
    outputChatBox("* Welcome .",source,255,255,0)    
    triggerClientEvent(source,"onJoin",source) 
    else 
    return false 
    end 
end

Source is the resourceRoot and not a payer. OnResourceStart event doesn't ever have a player as source.
