Ersatz PAPI in non-player event

[dxcf]

So I was trying to set up a scoreboard which shows stats of the player, in the placeholder part I use Ersatz then it says There's no player in a periodical event then I switched to function (Skellett's scoreboard) then I got another error saying There's no player in a function event

Does anyone know how to fix?

function updateBoard(p: player):
    set {tps} to placeholder "server_tps"
    set {joins} to placeholder "server_unique_joins"
    setSlot({_p}, "Test", 10, "&7&m+---------------------+")
    setSlot({_p}, "Test", 9, "&7» &e&lPlayer")
    setSlot({_p}, "Test", 8, "  &7Name: &e%{_p}%")
    setSlot({_p}, "Test", 7, "  &7Balance: &e%{_p}'s balance%")
    setSlot({_p}, "Test", 6, "     ")
    setSlot({_p}, "Test", 5, "&7» &e&lServer")
    setSlot({_p}, "Test", 4, "  &7Online players: &e%{online}%")
    setSlot({_p}, "Test", 3, "  &7TPS: &e%{tps}%")
    setSlot({_p}, "Test", 2, "  &7Unique Joins: &e%{joins}%")
    setSlot({_p}, "Test", 1, "&7&m+---------------------+")
