Trouble with data saving

Help and Feedback Scripting Support
#1

hey guys!
I am using some kind of “player handler”
But, i’m having a trouble, data isn’t saving :gorilla:
This is the module;

local tmp = require(script.profile)
local module = {}
local DataHandler = require(script.Parent.Datastore)
module.__index = module

function module.getplayer(plr)
	return module[plr] or module.new(plr)
end

function module.new(plr)
	assert(plr ~= nil,"plr's nil.")
	local self = setmetatable(tmp,module)
	module[plr] = self
	self.Player = plr
	return self
end

-- // DATA

function module:UpdateData(Information)
	self.ToSave = Information
end

function module:SaveData()
	print("Saving data.")
	DataHandler.SaveData(self.Player.UserId,self.ToSave)
end

function module:GetData()
	local data = DataHandler.GetData(self.Player.UserId)
	if (data) then
		return data
	end
	print(data)
 return nil
end

Data keeps printing nil.

This is data template or “tmp” in code;

return {
	ToSave = {
		Races = {
			["Winned Races"] = 0;
		};
		Rank = 0;
		Cash = 0;
		XP = 0;
		SelectedCar = 'V5Buggy';
		Vehicles = {
			["V5Buggy"] = {
				VehicleTexture = '';
			};
		};
	};
	NonSaving = {
		InRace = false;
	}
}

This is where I call the Save

Players.PlayerAdded:Connect(function(Player)
	-- // Retreiving Data
	local PlayerStorage = PlayersHandler.getplayer(Player)
	local Data = PlayerStorage:GetData()
	-- // Player leaving/ data saving.
	local connection
	connection = Players.PlayerRemoving:Connect(function(P)
		if (Player == P) then
			connection:Disconnect()
		end
		PlayerStorage:SaveData()
	end)
end)

For those interesed, this is the Data Module;

Data module 
local DSS = game:GetService("DataStoreService")
local Datastore = DSS:GetDataStore("DATA - PlayerStorage")
local data = {}

function data.SaveData(Key,ToSave)
	local Attempts = 0
	repeat
		local suc,er = pcall(function()
			Datastore:UpdateAsync(Key,function(Old)
				return ToSave or Old
			end)
		end)
		if (suc) then
			print("Successfully saved data.")
			break
		else
			warn(er,suc)
		end
		Attempts += 1
		wait(1)
	until not suc or Attempts >= 3
end

function data.GetData(key)
	local suc,result = pcall(Datastore.GetAsync,Datastore,key)
	if (suc) then
		if (result) then
			return result
		end
	else
		warn(suc)
		return data.GetData(key)
	end
	return nil
end

return data

Any idea why it’s not saving data? D:

it was fixed, i wasn’t passing a argument at :GetData lol.
