How do I fix this RemoteEvent script? I just started to learn how to use RemoteEvents. [Answered] [closed]

Hello, so I started to learn how to use RemoteEvents and I have a problem. Can I get some help? Output : 14:00:54.333 - FireClient: player argument must be a Player object 14:00:54.333 - Stack Begin 14:00:54.333 - Script 'Workspace.Values.playerDied.Script', Line 10 14:00:54.333 - Stack End and my script that :FireClient() :

local event = workspace.plrDied
local val = script.Parent
local player = game.Players.LocalPlayer
event.OnServerEvent:connect(function()
    val.Value = true
end)

script.Parent.Changed:connect(function()
    if script.Parent.Value == true then
        workspace.plrDiedUI:FireClient(player)
    end
end)

If you need more info please tell me. I'm hoping for some help.
