FindChangeByList - Javascript Error Number: 17

Hi Everyone,

I tried doing a search for this issue, but couldn't find anything newer than 2018, and none of the solutions discussed there solved my problem.  

I create a monthly magazine in InDesign, and set it all up to build a Table of Contents at the end.  Of course, a lot of formatting changes need to be made to the ToC after the fact, so I set up a BUNCH of grep find/change functions.  But I wanted to try and set it up to be a one and done type of thing, so I set up the findchangebylist.txt file using the Record Find Change script written by Martin Fisher.  

When I ran it, it appeared to run some of the find/changes in the script, but definitely not the first one, and then I got JavaScript Error Number 17.  I removed the commas from the beginning that were created by the recording script, as suggested in this post, but the error persisted and didn't change.  

Any help figuring out what I'm missing or doing wrong would be greatly appreciated.

Thank you.
