I'm making a shop which sells gems, you click a button on a GUI and it does pop up with the prompt to buy the Dev Product. My issue is that on the server the script for the management of the Dev Product is not working

local MarketplaceService = game:GetService("MarketplaceService")
MarketplaceService.ProcessReceipt = function(receiptInfo)
print("purchase")	
	local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
	if not player then
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end
	
	if receiptInfo.PurchaseId == 1138648796 then
	if player then
		local PlayerData = Data:get(player)
		PlayerData.Gems += 1000
		remotes.Update:FireClient(player)
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted
	end
	if receiptInfo.PurchaseId == 1138648972 then
		if player then
			local PlayerData = Data:get(player)
			PlayerData.Gems += 2500
			remotes.Update:FireClient(player)
		end
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end
end
