Why does my script stop Datastore2 making a purchase dev product?

MarketplaceService.ProcessReceipt = function(ReceiptInformation)
	local Player = Players:GetPlayerByUserId(ReceiptInformation.PlayerId)
	local DataPurchases = DataStore2('DataPurchases',Player)
	
	local playerProductKey = ReceiptInformation.PlayerId .. "_" .. ReceiptInformation.PurchaseId
	local purchased = false
	
	local success, errorMessage = pcall(function()
		purchased = DataPurchases:Get(playerProductKey)
	end)
	
	print('1') -- prints 1


		
	if success and purchased then
		return Enum.ProductPurchaseDecision.PurchaseGranted
	elseif not success then
		error("Data store error:" .. errorMessage)
	end
	
	
	print('2') -- DOES NOT PRINT 2 which means it stops here
 

	local player = Players:GetPlayerByUserId(ReceiptInformation.PlayerId)
	if not player then
		-- The player probably left the game
		-- If they come back, the callback will be called again
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end

	local handler = ProductFunctions[ReceiptInformation.ProductId]
 
	-- Call the handler function and catch any errors
	
	print('3')


	local success, result = pcall(handler, ReceiptInformation, player)
	
	if not success or not result then
		warn("Error occurred while processing a product purchase")
		print("\nProductId:", ReceiptInformation.ProductId)
		print("\nPlayer:", player)
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end
	
		print('4')
	
		local success, errorMessage = pcall(function()
			DataPurchases:Set(playerProductKey, true)
			DataPurchases:Save()
		end)
			
			
	if not success then
		error("Cannot save purchase data: " .. errorMessage)
	end
 
	print('Done')
	-- IMPORTANT: Tell Roblox that the game successfully handled the purchase
	return Enum.ProductPurchaseDecision.PurchaseGranted
	
end

I think it stops at around line 16 or 20
