Problems with datastores

I’m trying to fix this error, when I play, I get:

Argument 2 missing or nil

In addition, I’m not sure how to test a PlayerRemoving event.

Here is my code:

local DataStoreService = game:GetService("DataStoreService")
local CurrentLevels = DataStoreService:GetDataStore("CurrentLevels")

local function AddBoard2Player(player)
	local board = Instance.new("Model",player)
	board.Name = "leaderstats"

	local money = Instance.new("IntValue", board)
	money.Name = "Level"
	money.Value = 1
	local data
	local succes, errormessage = pcall(function()
		data = CurrentLevels:SetAsync(player.UserId.."-Level")
	end)
	if succes then
		money.Value = data
	else
		print("Error saving")
		warn(errormessage)
	end
	
end


local function SaveData(player)
	local succes, errormessage = pcall(function()
		CurrentLevels:SetAsync(player.UserId.."-Level",player.leaderstats.Level.Value)
	end)

	if succes then
		print("PlayerData Saved!")
	else
		print("There was a problem saving the data")
		warn(errormessage)
	end
end
game.Players.PlayerAdded:Connect(AddBoard2Player)
game.Players.PlayerRemoving:Connect(SaveData)

data = CurrentLevels:SetAsync(player.UserId.."-Level")
:SetAsync() must have a second parameter and you didn’t provide any.

I tried adding a parameter, now my level value is set to zero and doesn’t print or warn anything at all

local function AddBoard2Player(player)
	local board = Instance.new("Model",player)
	board.Name = "leaderstats"

	local money = Instance.new("IntValue", board)
	money.Name = "Level"
	money.Value = 1
	local data
	local succes, errormessage = pcall(function()
		data = CurrentLevels:SetAsync(player.UserId.."-Level",player.leaderstats.Level.Value)
	end)
	if succes then
		money.Value = data
	else
		print("Error saving")
		warn(errormessage)
	end
	
end

I want to ask real quick, are you trying to get data from datastore or write data to datastore?

#5

Write data to a datastore

#6

Because :SetAsync() doesn’t return anything so data variable is always nil.

#7

Then how else would I save the data?

#8

:SetAsync() does save the data but it doesn’t return anything as argument when it finishes it’s job so there is no need for that data variable.
Unless you intended to use :GetAsync() which only takes one parameter and returns the available data from the given key.

I kept the data variable but changed SetAsync() to GetAsync() now it works, thanks
