IE11 trailing comma issue in bundle.js

Created by: trustfall

Getting an error regarding line 965 of bundle.js, because of a trailing comma.

I took a screen of this on my VM. Basically, the app works fine on most browsers, but on my IE11 VM, it freaks out because of this trailing comma. It's under the 'ansi-html/index.js' module - I'm not entirely sure where to look for this. I am running node-sass with CRA exactly how it's described in the readme, and also running react-scripts-ts.
