Cannot store Array in data store. Data stores can only accept valid UTF-8 characters

Well, I’ve seen some topics about this error on the DevForum but I don’t understand what I have to do

Script 
local Players = game:GetService("Players")
local RS = game:GetService("ReplicatedStorage")
local AFK = RS.Events.AFK
local Warn = RS.Events.AssetsLoadedOutput

local Titles

local DataStoreService = game:GetService("DataStoreService")

local TitlesData = DataStoreService:GetDataStore("TitlesData")

local function ChangeAFKProperty(Player, Value)
	Player:SetAttribute("AFK", Value)
	-- print("AFK = ", Value)
end

local function AssetsLoaded(Player)
	Player:SetAttribute("AssetsLoaded", true)
end

Players.PlayerAdded:Connect(function(Player)
	local stats = Instance.new("Folder")
	stats.Parent = Player
	stats.Name = "leaderstats"
	
	local Owls = Instance.new("IntValue")
	Owls.Value = 8000
	Owls.Name = "Owls"
	Owls.Parent = stats
	
	Titles = Instance.new("Folder")
	Titles.Name = "Titles"
	Titles.Parent = Player
	
	local Data = {"nothing"}
	local success, errormessage = pcall(function()
		Data = TitlesData:GetAsync(Player.UserId) 
	end)
	
	if success then 
		for _,Object in pairs(Data) do
			Object.Parent = Titles
		end
	else
		print("Error while getting your data")
		warn(errormessage)
	end
	
	Player:SetAttribute("AFK", false)
	Player:SetAttribute("InGame", false)
	Player:SetAttribute("AssetsLoaded", false)
	Player.CharacterAdded:Connect(function()
		Player:SetAttribute("InGame", false)
		Player:SetAttribute("AssetsLoaded", false)
	end)
end)

game.Players.PlayerRemoving:Connect(function(Player)
	local TitleData = {}
	for _,Object in pairs(Titles:GetChildren()) do
		table.insert(TitleData, Object)
	end
	TitlesData:SetAsync(Player.UserId, TitleData)
end)

AFK.OnServerEvent:Connect(ChangeAFKProperty)
Warn.OnServerEvent:Connect(AssetsLoaded)

There are some extra things about the Game, but the main thing is that Datastore doesn’t save the Titles.

Context: When buying an item, the server adds the Item to the Player in a folder, the Client detects this and adds it to his Inventory with ChildAdded, and when the Player exits I want everything inside that Folder to save, but it gives this error.
What can I do?

You can’t save game objects to a datastore, you can save their name, or some other unique id, and when you load a player, check the name that contains his datastore and give him the right things

#3

You’re trying to save instances into a Datastore, in the connection to PlayerRemoving.

Datastores can’t hold instances. To store them, we do serialization (storing the properties with a table). Basically, you need to serialize Object and then store it.

#4

So I have to load the features and instantiate them? In this case, Titles.

#5

yes, like

Save

TitlesData:SetAsync(Player.UserId, {
    "Title1",
    "Title2",
})
--[[
    You save a table of strings that the player has
]]

Load

local Data = TitlesData:GetAsync(Player.UserId)
for _, value in pairs(Data) do
   if value == "Title1" then
     -- TODO: Creating Title1 instance
   elseif value == "Title2" then
     -- TODO: Creating Title2 instance
   end
end

Can’t you do x:GetFullName()? To get it into the table?

Like, in general I just need the Name, nothing more, nothing less, is it possible for me to use the Array only to save the Name, does the DataStore accept it?

#8

Yeah. If you want the path then x:GetFullName() probably works.
