scale8 recently archived their GitHub repo without explanation and right after that the url for a GDPR opt-in list they were using changed. The product is now dead because the code doesn't handle the situation where that file might not be available.

(Scale8 is a web analytics and tag management software like google analytics)

I forgot to mention this error check even breaks the admin dashboard meaning you can't even see historical data anymore.

Just in case anybody else is in the same boat you can change the url in the code to the new one yourself.
