I have a code gui which whenever the player redeems a code it creates a bool value in the code folder and it saves, but whenever I redeem a code it gives a warning that says datatstore request was added to queue, which prevents it from saving... 

local data = game:GetService("DataStoreService"):GetDataStore("codes")

game.Players.PlayerAdded:Connect(function(player)
	local key = "codes-"..player.userId
	local folder = Instance.new("Folder",player)
	folder.Name = "Codes"
	local save = data:GetAsync(key)
	if save then
	for i = 1, #save do
		local temp = Instance.new("BoolValue",folder)
		temp.Name = save[1]
		end
	end
end)

game.ReplicatedStorage.Remote.Redeem.OnServerEvent:Connect(function(player,code)
    local reward = player:FindFirstChild("leaderstats")
    local r = reward.Gold
    local key = "codes-"..player.userId

    if code == "Release"  then
    if player.Codes:FindFirstChild(code) == nil then
    local bool = Instance.new("BoolValue")
    bool.Parent = player:FindFirstChild("Codes")
    bool.Name = code
    r.Value = r.Value + 300
player.PlayerGui:FindFirstChild("SubGui").Code.CodeHandler.Text = "Redeemed!"
wait(3)
player.PlayerGui:FindFirstChild("SubGui").Code.CodeHandler.Text = "Type your code here"
end
end

	local activated = {}
	for i,v in pairs(player.Codes:GetChildren()) do
		if v:isA("BoolValue") then
			table.insert(activated, v.Name)
			data:SetAsync(key,activated)
		end
	end
end)
