hey, im trying to make a datastore system for my storage. but there is a little problem. i keep getting this error
“104: Cannot store Array in data store. Data stores can only accept valid UTF-8 characters.”
im not rlly good at datastores, so i have no clue what it means. i tried fixing it but… didnt work.
(this script isnt mine, i just modified it)

game.Players.PlayerAdded:Connect(function(player)
	local storage = player:WaitForChild("Storage")
	local load = ds:GetAsync("User_"..player.UserId) or {}
	if type(load) == "table" then
		for i, v in pairs(load) do
			for name, value in pairs(v) do
				
				local object = Instance.new("ObjectValue")
				object.Parent = storage
				object.Name = name
				object.Value = value
				
			end
		end
	else
		load = {}
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local data  = {}
	local storage = player:WaitForChild("Storage")
	for i, v in pairs(storage:GetChildren()) do
		if v:IsA("ObjectValue") then
			local nameAndVal = {}
			nameAndVal[v.Name] = v.Value
			table.insert(data, nameAndVal)
		end
	end
	local res = ds:SetAsync("User_"..player.UserId, data)
end)

game:BindToClose(function()
	for i, player in pairs(game.Players:GetPlayers()) do
		local data  = {}
		local storage = player:WaitForChild("Storage")
		for i, v in pairs(storage:GetChildren()) do 
			if v:IsA("ObjectValue") then
				local nameAndVal = {} 
				nameAndVal[v.Name] = v.Value
				table.insert(data, nameAndVal)
			end
		end
		local res = ds:SetAsync("User_"..player.UserId, data)
	end
end)

if you have any ideas why it doesnt work please comment below.

It means that it can only use standard keys and symbols when storing data.

Using non-standard characters may not work with the datastore’s compatibility

soooo, its trying to set the table. so it cant save tables?

You’re trying to save instances through ObjectValues. You can’t save instances in DataStores.

i guess that makes sence, ill try fixing it
