Why doesnt my tool saving script work when you rejoin the game?

When I leave with a tool in my inventory and join back it simply does not give me the tool

local ds = game:GetService("DataStoreService"):GetDataStore("ToolSave")
 game.Players.PlayerAdded:connect(function(plr)
 local key = "id-"..plr.userId
 pcall(function() 
    local tools = ds:GetAsync(key)
     if tools then 
        for i,v in pairs(tools) do 
            local tool = game.ServerStorage.Tools:FindFirstChild(v)
             if tool then
                 tool:Clone().Parent = plr:WaitForChild("Backpack")
                 tool:Clone().Parent = plr:WaitForChild("StarterGear")
             end
         end
     end 
end) 
end) 
game.Players.PlayerRemoving:connect(function(plr) 
    local key = "id-"..plr.userId 
    pcall(function()
         local toolsToSave = {}
         for i,v in pairs(plr.Backpack:GetChildren()) do
             if v then 
                table.insert(toolsToSave,v.Name)
             end 
        end
         ds:SetAsync(key,toolsToSave)
     end) 
    end)
