Issue with newest version of sheetrock

[amagistrale]

I was having an issue using the newest version of sheetrock to collect data out of my google sheet to display as a pop up on a mapbox map. I was using this script for my source:

<script src="https://unpkg.com/[email protected]/dist/jquery.slim.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/sheetrock.min></script>

And I was given the attached error. I was able to get my code working with an older version of sheetrock. I am fairly new to using javascript so this may have just been something I was doing, but I thought I would mention it.
