I can't store a player's inventory in data store?

I know how to use data store but, here I am trying out something new that I have not done before. I want to give the player a wooden sword if they have nothing in their data store. Also I can't load in the data store.

local swordsFolder = script.Parent

local DSS = game:GetService("DataStoreService")
local DS = DSS:GetDataStore("ToolStore")
local Ss = game:GetService("ServerStorage")

game.Players.PlayerAdded:Connect(function(plr)
	
	local char = plr.Character or plr.CharacterAdded:Wait()
	
	local inv = Instance.new("Folder",plr)
	inv.Name = "Inventory"
	
	local data
	local s, e = pcall(function()
		data = DS:GetAsync(plr.UserId.."-Tools")
	end)
	
	if s then
		if data == nil then
			local clone = swordsFolder.WoodenSword:Clone()
			clone.Parent = plr:WaitForChild("BackPack")
		end
		local invTable = {}
		table.insert(invTable,data)
		print(plr.Name.." - Tool store successful!")
	else
		warn(e)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	
	local invTable = {}
	
	for i,v in pairs(plr.Inventory:GetChildren()) do
		table.insert(invTable,#invTable,v)
	end
	
	local s, e = pcall(function()
		DS:SetAsync(plr.UserId.."-Tools",invTable)
	end)
	
	if s then
		print(plr.Name.." - Tool data store successful!")
	else
		warn(e)
	end
end)

Thanks for the help. It would be very useful if you found out what the problem is and how I can get over it.

Also, the output has no error in case you were going to ask.
