Migration failing at Step 3

Hello, I am trying to migrate from Magento 1.9.10 to Magento 2.1.7 and the first two steps went successfully and then I begun to get this error message.
Having searched around the forum I added the following to my Mage1AttributeSet.php

public function primaryKey() {
return array('attribute_set_id');

However when I try to run it now I keep getting a Gateway timeout error. Is there a way to skip this step and proceed to migrating products?

Hi Matthew,
It’s pity that our Lite version is available for Magento 2.0.7 only. 
Actually, the Lite version is mainly for testing purpose only, as its codebase is outdated. If you wish to make a test migration, please note:
-- It is not ready for NGINX web server
-- Your Magento 2.0.7 must be a fresh installation
-- And it comes with limited feature sets, compared to our Pro version.
We highly recommend you consider our Pro version, it will save you pretty much time. In case you missed, here’s the latest update version 3.0.9 released a few days ago. You can learn more about UB Data Migration Pro version 3 via this tutorial video: https://youtu.be/R4UBLe2kf-I
Besides, below are recent case studies for your reference: 
-- Winetasting.com – Migrate 382,047 customer entities to Magento 2
-- Freelaunch.nl -- migrate 230,000 products to Magento 2
PS. Please note the old script we distributed via Github is no longer maintained.
