Metatables not working

[6Square4 (Garchy)]

Basically, i call a function named playerJoined which returns data from my module, but data:test() isn’t working despite it being defined (i might be understanding this wrong)

heres the module:

local Data = {};
Data.__index = Data;

Data.Profiles = {};

local Modules = script.Parent;

local ProfileService = require(Modules.ProfileService);

local DataStore = ProfileService.GetProfileStore({
	Name = script:GetAttribute("DataStoreName"),
	Scope = script:GetAttribute("Scope");
}, {
	Bux = 30000,
	Items = {},
	Gems = 0,
	Tix = 0,
	Cases = 1,
})

function Data.PlayerJoined(player)
	warn("LOADING")
	local profile = DataStore:LoadProfileAsync(tostring(player.UserId), false, "ForceLoad");
	local self = {};
	
	if profile and player then
		warn("Loading 1/4")
		if player.Parent then
			warn("Loading 2/4")
			profile:AddUserId(player.UserId);
			profile:Reconcile();
			
			profile:ListenToRelease(function()
				player:Kick("Your data is released.");
				Data.Profiles[player.UserId] = nil;
			end)
			
			if Data.Profiles[player.UserId] then
				Data.Profiles[player.UserId]:Release();
				player:Kick("Your data was already loaded in this session. Please rejoin.");
			else
				warn("Loading 3/4")
				self.__index = self;
				self = profile;
				self = setmetatable(self, {});
				Data.Profiles[player.UserId] = self;
				warn("Loaded 4/4");
				return self;
			end
		end
	end
	return self;
end

function Data:test()
	print(self);
end

return Data;

Script:

local Modules = script.Parent.Parent.Modules;

local rakeData = require(Modules.RakeData);


function playerAdded(player)
	local data = rakeData.PlayerJoined(player);
	warn(data)
	data:test();
end

for i, v in pairs(game.Players:GetPlayers()) do
	playerAdded(v);
end
game.Players.PlayerAdded:Connect(playerAdded)

Error: ServerScriptService.Scripts.Module Execution:9: attempt to call missing method 'test' of table

That is because you’re not setting the metatable of the new object you’re making to Data. You should define self as setmetatable(self, Data). Then do everything as normal.
