Link Checker Error - Config is not defined

[Harry Thurston]

Hi - 

I am trying to set-up a copy of the below link checker script in a couple of accounts, but receive the same error when trying to run them - ReferenceError: CONFIG is not defined (line 62)

https://developers.google.com/google-ads/scripts/docs/solutions/link-checker

I have copied the set-up + code for each of the 3x files exactly, changing only the email address and GDoc links. 

Any advice much appreciated!
