My IntValues on my game wont save?

So I made an OnServerEvent where when u buy something it gives you a value of 1 so it can save your items but when I wrote this script that worked for all my leader stats it didn't work for: Error: DataStore request was added to the queue. If the request queue fills, further requests will be dropped. Try sending fewer requests.

local DataStoreService = game:GetService("DataStoreService")

local playerData = DataStoreService:GetDataStore("PlayerData")



local function onPlayerJoin(player)  -- Runs when players join
local SwordBools = Instance.new("Folder")
SwordBools.Name = "SwordBools"
	SwordBools.Parent = player


	local WoodKnife = Instance.new("IntValue")
	WoodKnife.Name = "OwnWKnife"
	WoodKnife.Parent = player.SwordBools


	local Knife = Instance.new("IntValue")
	Knife.Name = "OwnKnife"
	Knife.Parent = player.SwordBools

	



	local data
	local success,errormsg = pcall(function()
	    data = playerData:GetAsync(playerUserId)
	end)
	if success then
	    if data then
	        WoodKnife.Value = data.OwnWKnife
	        Knife.Value = data.OwnKnife
	else
	    WoodKnife.Value = 0
	        Knife.Value = 0
	end


		
	end

end



local function create_table(player)

	local player_stats = {}

	for _, stat in pairs(player.SwordBools:GetChildren()) do

		player_stats[stat.Name] = stat.Value

	end

	return player_stats

end



local function onPlayerExit(player)  --Runs when players exit



	local player_stats = create_table(player)

	local success, err = pcall(function()

		local playerUserId = "Player_" .. player.UserId

		playerData:SetAsync(playerUserId, player_stats) --Saves player data

	end)



	if not success then

		warn('Could not save data!')

	end

end



game.Players.PlayerAdded:Connect(onPlayerJoin)

game.Players.PlayerRemoving:Connect(onPlayerExit)
