Inventory system seems to have a flaw

Hello,

I made an inventory system that receives your tools from a specific folder, which is located inside the player. The issue is, sometimes when I join my game for the sake of testing, I don’t receive my tools. The weird thing is, I have a print statement that prints the user’s inventory. The print statement always seems to print the user’s inventory flawlessly, however sometimes user doesn’t receive his/her items, which is a huge problem. Any suggestions?

Code:

local DataStore = game:GetService("DataStoreService")
local InventoryDS = DataStore:GetDataStore("InventoryDS")
local ToolsFolder = game.ServerStorage.Tools

--When the player is added
game.Players.PlayerAdded:Connect(function(player)
local InvFolder = Instance.new("Folder")
InvFolder.Name = "InvFolder"
InvFolder.Parent = player

local success, errormessage = pcall(function()
	inventory = InventoryDS:GetAsync(player.UserId) or {}
	for i,v in pairs(inventory) do
		if ToolsFolder:FindFirstChild(v) then
			ToolsFolder[v]:Clone().Parent = player.Backpack
			ToolsFolder[v]:Clone().Parent = player.InvFolder
		end
	end
end)

if success then
	print(player.Name.." - Data received upon join.[INV]")
	print(inventory)
else
	print(player.Name.." - Data couldn't be received upon join.[INV]")
	warn(errormessage)
end

end)

--When player is removed
game.Players.PlayerRemoving:Connect(function(player)
local inventory = {}

for i,v in pairs(player.InvFolder:GetChildren()) do
	table.insert(inventory, v.Name)
end

local success, errormessage = pcall(function()
	InventoryDS:UpdateAsync(player.UserId, function(new)
		return inventory
	end)
end)

if success then
	print(player.Name.." - Data saved upon removal[INV]")
else
	print(player.Name.." - Data couldn't be saved upon removal.[INV]")
	warn(errormessage)
end
end)

--When server shutdowns
game:BindToClose(function()
local players = game.Players:GetPlayers()
local inventory = {}
for i = 1, #players do
	for i, v in pairs(players[i].InvFolder:GetChildren()) do
		table.insert(inventory, v.Name)
	end

	local success, errormessage = pcall(function()
		InventoryDS:UpdateAsync(players[i].UserId, function(new)
			return inventory
		end)
	end)
	wait(6)
	if success then
		print(players[i].Name.." - Data saved upon removal[INV]")
	else
		print(players[i].Name.." - Data couldn't be saved upon removal.[INV]")
		warn(errormessage)
	end
end
end)

Theres nothing saving the data, you’re just loading non existant data that hasn’t been saved

Also you can only save UTF-8 characters such as strings, Vector3, Bools, Numbers etc you can’t save entire instancs

local DataStore = game:GetService("DataStoreService")
local InventoryDS = DataStore:GetDataStore("InventoryDS")
local ToolsFolder = game.ServerStorage.Tools

game.Players.PlayerAdded:Connect(function(player)
local InvFolder = Instance.new("Folder")
InvFolder.Name = "InvFolder"
InvFolder.Parent = player
local playerId = "Player_"..player.UserId
local success, errormessage = pcall(function()
	inventory = InventoryDS:GetAsync(playerId)
	for i,v in pairs(inventory) do
		if ToolsFolder:FindFirstChild(v) then
			ToolsFolder[v]:Clone().Parent = player.Backpack
			ToolsFolder[v]:Clone().Parent = player.InvFolder
		end
	end
end)

if success then
	print(player.Name.." - Data received upon join.[INV]")
	print(inventory)
else
	print(player.Name.." - Data couldn't be received upon join.[INV]")
	warn(errormessage)
end

end)

game.Players.PlayerRemoving:Connect(function(player)
   local playerId = "Player_"..player.UserId
   local weapons = {}
   for i, tool in pairs(InvFolder:GetChildren()) do
     if tool:IsA("Tool") then
       table.insert(weapons, i, tool.Name)
     end
   end
   InventoryDS:SetAsync(playerId, weapons)
end)

I might be a bit wrong but hopefully this helps

There’s also the data saving block, I didn’t publish it because I don’t think its related to that one, but I guess I will edit my first post now.
