OK, it keeps saying the error

This is my script:

local ds = game:GetService("DataStoreService"):GetOrderedDataStore("Main")

game.Players.PlayerAdded:connect(function(player)
	local leaderstats = Instance.new("Folder",player)
	leaderstats.Name="leaderstats"
	local grasscut = Instance.new("IntValue",leaderstats)
	grasscut.Name = "Grass Cut"
	local money = Instance.new("IntValue",leaderstats)
	money.Name = "Money"
	
	local tableOfItems = {}
	local s,f=pcall(function()
		for i,v in pairs(ds:GetAsync(player.UserId)) do
			tableOfItems[#tableOfItems+1]=v
		end
	end)
	if s then
		for i,v in pairs(tableOfItems) do
			if v.Name=="Banned" then
				if v==true then
					player:Kick()
				end
			end
			if v.Name=="grasscut" then
				grasscut.Value = v
			end
			if v.Name=="items" then
				for i,v in pairs(v) do
					game.ServerStorage.Items[v]:Clone().Parent = player.Backpack and player.StarterGear
				end
			end
		end
	else
		print("Failed to get "..player.Name.."'s inventory, perhaps a new player? Reason:")
		error(f)
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	local items = {}
	for i,v in pairs(player.StarterGear:GetChildren()) do
		items.insert(v.Name)
	end
	local itemsToSave={["banned"]=false,["grasscut"]=player.leaderstats["Grass Cut"].Value,["items"]=items,["money"]=player.leaderstats.Money.Value}
	local s,f=pcall(function()
		ds:SetAsync(player.UserId,itemsToSave)
	end)
	if s then
		print(player.Name.."'s inventory has been saved!")
	else
		print("Could not save "..player.Name.."'s inventory, reason:")
		error(f)
	end
end)

Can somebody please tell me my mistake? Was it the tables? I'm not sure.
