Module or Script doesnt replicate instance

Help and Feedback Scripting Support

There’s this module where you can save Instances into Datastores which is very useful,
it seems to work on a test server, but in an actual game it doesn’t replicate the item
It doesn’t show any errors whatsoever.

Help is appreciated!

local instanceStore = require(game.ServerScriptService.Services.Converter)
local dataService = game:GetService("DataStoreService")
local collectedData = dataService:GetDataStore("collectedCubes")
local players = game.Players
local storage = game.ReplicatedStorage.cubesFound

players.PlayerAdded:Connect(function(person)
	local check, ex = pcall(function()
		wait(5)
		warn("i starty")
		instanceStore:ConvertToInstance(collectedData:GetAsync('collectedCubes')).Parent = storage
	end)

	if check then
		print("All collected items from "..person.UserId.." have been converted into instances.")
		storage:SetAttribute("num",true)
	else
		warn(ex)
	end
end)

for _, v in pairs(workspace.Cubes:GetChildren()) do
	if v:IsA("BasePart") then
		v.Touched:Connect(function(hit)
			local person = players:GetPlayerFromCharacter(hit.Parent)
			print("Player_"..person.Name.." found a "..v.Name)
			storage:SetAttribute("num",true)
			
			
			v.Parent = storage
		end)
	end
end

players.PlayerRemoving:Connect(function(person)
	
	if storage:GetAttribute("num") == false then
		print("None SAVED.")
	end
	
	local check, errormessage = pcall(function()
		collectedData:SetAsync(storage:GetChildren(), instanceStore:ConvertToSaveable(storage, true))
	end)

	if check then
		print(person.Name.."'s data had been kept.")
	else
		warn(errormessage) 
	end
end)
