you need to assign MP
ex: MP.RegisterEvent("onPlayerAuth","onPlayerAuth")

full code is:

function onInit()
print("guestControl Loaded")
MP.RegisterEvent("onPlayerAuth","onPlayerAuth")
end

function onPlayerAuth(name, role, isGuest)

print("Checking " .. name .. " for guest status...")
if isGuest then
	return "يou have to be logged in to join the server."
end

end
