Leaderboard script isnt working

  1. What do you want to achieve? Fix my leaderboard script

  2. What is the issue? My leaderboard is giving me this error below

  3. What solutions have you tried so far? I tried to look at DevHub but i din’t found a solution.

Script:

local DataStoreService = game:GetService("DataStoreService")
local KillsLeaderBoard = DataStoreService:GetOrderedDataStore("KillsLeaderBoard")

local function updateLeaderboard()
	local success, errorMessage = pcall(function()
		local Data = KillsLeaderBoard:GetSortedAsync(false,5)
		local killPage = Data:GetCurrentPage()
		for rank, data in ipairs(killPage) do
			local userName = game.Players:GetNameFromUserIdAsync(tonumber(data.key))
			local Name = userName
			local kills = data.Value
			local IsOnLeaderboard = false
			for i,v in pairs(game.Workspace.GlobalLeaderboard.LeaderboardGui.Holder:GetChildren()) do
				if v.Player.Text == Name then
					IsOnLeaderboard = true
					break
				end
			end
			if kills and IsOnLeaderboard == false then
				local newLbFrame = game.ReplicatedStorage:WaitForChild("LeaderboardFrame"):Clone()
				newLbFrame.Player.Text = Name
				newLbFrame.Kills.Text = kills
				newLbFrame.Position = UDim2.new(0, 0, newLbFrame.Position.Y.Scale + (0.8 * #game.Workspace.GlobalLeaderboard.LeaderboardGui.Holder:GetChildren()), 0)
				newLbFrame.Parent = game.Workspace.GlobalLeaderboard.LeaderboardGui.Holder
				
			end
		end
	end)
	if not success then
		print(errorMessage)
	end
end

while true do
	for _, player in pairs(game.Players:GetChildren()) do
		KillsLeaderBoard:SetAsync(player.UserId, player.leaderstats.Kills.Value)
		
	end
	for _, frame in pairs(game.Workspace.GlobalLeaderboard.LeaderboardGui.Holder:GetChildren()) do
		frame:Destroy()
	end
	updateLeaderboard()
	print("updating")
	
	wait(10)
end

Whats wrong on this script?
