Roblox - Argument 1 缺失或为空

我正在编写一个脚本，当你触摸角色的碰撞箱时，会出现某些聊天信息，但输出窗口会显示"Argument 1 missing or nil"。

代码:

local debounce = false

game.Workspace.RowanAsleep.RowanAsleepHitbox.Touched:Connect(function(hit)

    if not debounce then
        debounce = true
        if game.Players:GetPlayerFromCharacter(hit.Parent)then
            game.ReplicatedStorage.RowanTalking.RowanSleeping:FireClient()
        end
        wait(2)
        debounce = false
    end
end)
