Tool saving script fails to load/save data or clone tools into the backpack. What's wrong? [FIXED]

Script maybe doesn't successfully save data. It loads it in too (Maybe this is where it goes wrong), but the tools do not clone into the backpack. What is the problem?

local dataStoreService = game:GetService("DataStoreService")
local toolStore = dataStoreService:GetDataStore("TOOLS")
--local inventoryStore = dataStoreService:GetDataStore("GuiInventory")
--local backpackstore = dataStoreService:GetDataStore("Backpack")
game.Players.PlayerAdded:Connect(function(player)
    local data = nil
    local sucess, errormessage = pcall(function()
        data = toolStore:GetAsync(player.UserId)
    end)
    if sucess then
        if data[#data] then
            for i,v in pairs(data) do
                local tool = game:WaitForChild("ReplicatedStorage").Tools:FindFirstChild(data[i])
                print(tool, data[i])
                if tool then
                    tool:Clone().Parent = player.Backpack
                end
            end
        end
    else
        warn("Datastore error!")
        error(errormessage)
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    local toolsToSave = {}
    for key, object in pairs(player.Backpack:GetChildren()) do
        table.insert(toolsToSave, object.Name)
    end
    local sucess, errormessage = pcall(function()
        toolStore:SetAsync(player.UserId, toolsToSave)
    end)
    if sucess then
        print(" ToolData Sucess!")
        print(player.Name .. ",s data has been saved, its ", game:GetService("HttpService"):JSONEncode(toolsToSave))
    else
        warn("Datastore error!")
        error(errormessage)
    end
end)
