My code:

local DataStoreService = game:GetService("DataStoreService")

local Data = DataStoreService:GetDataStore("TestDataStore")


game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local studs = Instance.new("IntValue")
	studs.Name = "Studs"
	studs.Parent = leaderstats
	
	local rebirths = Instance.new("IntValue")
	rebirths.Name = "Rebirths"
	rebirths.Parent = leaderstats
	
	local PlrID = "Player_"..player.UserId
	
	local getData
	
	local success, errormessage = pcall(function()
		 getData = Data:GetAsync(PlrID)
	end)
	
	if success then
		player.leaderstats.Studs.Value = data.Studs
		player.leaderstats.Rebirths.Value = data.Rebirths
	else
		print("Error loading data..")
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local PlrID = "Player_"..player.UserId
	
	local data = {
		Studs = player.leaderstats.Studs.Value;
		Rebirths = player.leaderstats.Rebirths.Value;
	}
	
	local success, errormessage = pcall(function()
		Data:SetAsync(PlrID, data)
	end)
	
	if success then
		print("✅ Data saved!")
	else
		warn("⚠ Error when saving data. Contact Xelb")
	end

My issue: ServerScriptService.DataStore:28: attempt to index nil with ‘Studs’

I feel like it has something to do with saving the table, but I’m unsure. Sorry if my code is weird. This is my first time working with datastores, and I’m trying to get the basics down.

Strange, I don’t get the error after copying the code, the only thing im getting error loading data

3

Maybe due to a first time creation on the DataStore? Cause you can’t load in data if it doesn’t exist

Possibly, here is how to fix it:

getData = Data:GetAsync(PlrID) or 0

I found the problem with your code, specifically this line here:

Your loaded data table is called getData, not data. So, in this case, data.Studs is nil.

Rewritten version code here, which works perfectly fine:

local DataStoreService = game:GetService("DataStoreService")

local Data = DataStoreService:GetDataStore("TestDataStore")

-- I made the loading and saving into a function, and they get called when needed.
function LoadData(Player)
	local leaderstats = Instance.new("Folder", Player)
	leaderstats.Name = "leaderstats"

	local studs = Instance.new("IntValue", leaderstats)
	studs.Name = "Studs"

	local rebirths = Instance.new("IntValue", leaderstats)
	rebirths.Name = "Rebirths"

	local PlrID = "Player_"..Player.UserId

	local getData
	local success, errormessage = pcall(function()
		getData = Data:GetAsync(PlrID)
	end)

	if success and getData then
		Player.leaderstats.Studs.Value = getData.Studs
		Player.leaderstats.Rebirths.Value = getData.Rebirths
	elseif success and not Data then
		-- If loading succeded, but no data is saved for the player
	elseif not success then
		print('⚠ Error loading data.')
	end
end

function SaveData(Player)
	local PlrID = "Player_"..Player.UserId

	local data = {
		Studs = Player.leaderstats.Studs.Value;
		Rebirths = Player.leaderstats.Rebirths.Value;
	}

	local success, errormessage = pcall(function()
		Data:SetAsync(PlrID, data)
	end)

	if success then
		print("✅ Data saved!")
	else
		warn("⚠ Error when saving data. Contact Xelb")
	end
end

game.Players.PlayerAdded:Connect(LoadData)
game.Players.PlayerRemoving:Connect(SaveData)

-- We have this here just in case the server closes for whatever reason
game:BindToClose(function()
	for i, v in pairs(game.Players:GetPlayers()) do
		SaveData(v)
	end
end)

Thank you so much! I was stuck on this for like an hour haha. Appreciate the help from both you and MasterGoat!
