ProcessReceipt not called/activated?

Hi, So I am making a code which handles pet devproducts and gamepasses. However, none of the print and warn functions are being called and I am sure that there are no other ProcessReceipt call backs. I used Ctrl + Shift + F to find it but there is only one script. The script is a module script ran by the server. Please help.

local RobuxServerModule = {}

--// Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local MPS = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local ServerStorage = game:GetService("ServerStorage")
local DataStoreService = game:GetService("DataStoreService")

--// Variables
local Modules = script.Parent
local gamepassBroughtEvent = ReplicatedStorage:WaitForChild("GameClient"):WaitForChild("Events"):WaitForChild("RemoteEvent"):WaitForChild("GamepassBrought")
local purchaseHistoryStore = DataStoreService:GetDataStore("PurchaseHistory")

--// Modules
local EggHandler = require(Modules:WaitForChild("EggServerHandler"))

local DevpassID = {
	
	--// Robux Egg
	["RobuxEgg1"] = {1173925524, function(plr) return EggHandler:OpenSpecialEgg(plr, "Robux Egg", "Buy1") end};
	["RobuxEgg2"] = {1173925574, function(plr) return EggHandler:OpenSpecialEgg(plr, "Robux Egg", "Buy3") end};
	["RobuxEgg11"] = {1174795856, function(plr) return EggHandler:OpenSpecialEgg(plr, "Robux Egg22", "Buy1") end};
	["RobuxEgg22"] = {1174795920, function(plr) return EggHandler:OpenSpecialEgg(plr, "Robux Egg22", "Buy3") end};
	["RobuxEgg111"] = {1174991529, function(plr) return EggHandler:OpenSpecialEgg(plr, "Carnival RobuxEgg", "Buy1") end};
	["RobuxEgg222"] = {1174991582, function(plr) return EggHandler:OpenSpecialEgg(plr, "Carnival RobuxEgg", "Buy3") end};
	["RobuxEgg1111"] = {1175442829, function(plr) return EggHandler:OpenSpecialEgg(plr, "Carnival Robux2", "Buy1") end};
	["RobuxEgg2222"] = {1175442851, function(plr) return EggHandler:OpenSpecialEgg(plr, "Carnival Robux2", "Buy3") end};
	["OmegaRobot1"] = {1174277414, function(plr) return EggHandler:OpenSpecialEgg(plr, "Omega Robot", "Buy1") end};
	["OmegaRobot2"] = {1174277535, function(plr) return EggHandler:OpenSpecialEgg(plr, "Omega Robot", "Buy3") end};
}

local function processReceipt(receiptInfo)
	warn("Processing Reciept")
	local playerProductKey = receiptInfo.PlayerId .. "_" .. receiptInfo.PurchaseId
	local purchased = false
	local success, errorMessage = pcall(function()
		purchased = purchaseHistoryStore:GetAsync(playerProductKey)
	end)
	if success and purchased then
		return Enum.ProductPurchaseDecision.PurchaseGranted
	elseif not success then
		error("Data store error:" .. errorMessage)
	end

	local player = Players:GetPlayerByUserId(receiptInfo.PlayerId)
	if not player then
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end

	local success, errorMessage = pcall(function()
		purchaseHistoryStore:SetAsync(playerProductKey, true)
	end)
	if not success then
		error("Cannot save purchase data: " .. errorMessage)
	end
	warn("Processing Reciept2")

	gamepassBroughtEvent:FireClient(player, receiptInfo.ProductId)
	return Enum.ProductPurchaseDecision.PurchaseGranted
end

function RobuxServerModule:Int()
	MPS.ProcessReceipt = function(receiptInfo)
		print("Hi")
		local plr = Players:GetPlayerByUserId(receiptInfo.PlayerId)
		if plr and receiptInfo then
			local success = false
			local idFound = false
			for devProductName, tbl in pairs(DevpassID) do
				if type(tbl) == "table" then
					local id,func = tbl[1],tbl[2]
					if id ~= nil and func ~= nil and type(func) == "function" then
						if receiptInfo.ProductId == id then
							idFound = true
							local functionFinised = func(plr)
							if functionFinised == false then
								warn("Something went wrong when", plr.Name, "was buying a developer product!", devProductName)
								success = false
							else
								-- send webhook if you want
								success = true
							end
							break
						end
					end
				end
			end
			if not idFound then
				local processedResult = processReceipt(receiptInfo)
				return processedResult
			end
			if success == true then
				gamepassBroughtEvent:FireClient(plr, receiptInfo.ProductId)
				return Enum.ProductPurchaseDecision.PurchaseGranted
			else
				return Enum.ProductPurchaseDecision.NotProcessedYet	
			end
		end
		return Enum.ProductPurchaseDecision.NotProcessedYet	
	end
end

return RobuxServerModule

Does any script require this ModuleScript and run the functions?

Yes, only one script calls this module

local RobuxServerModule = require(Modules:WaitForChild("RobuxServerModule"))
local AutoDeleteServerModule = require(Modules:WaitForChild("EggServerHandler"):WaitForChild("AutoDeleteServer"))
local TradeServerModule = require(Modules.TradeServerModule)

--// Int Modules
PetHandler:Int()
TradeServerModule:Int()
EggServerModule:Int()
RobuxServerModule:Int()

So I take it all of these modules process receipts?

No just one, RobuxServerModule

That’s odd, perhaps try putting this code in a separate place and see if the same problem occurs.

Ok I will try do that

(hhhhhhhhh)

Nope, not printing still. I made a server script and put the function in there and made the previous module require in comments but it still does not activate.
