attend to uncaught promise error in configuration.ts

When I have the console open, I often see something like this when launching the app

Uncaught (in promise) Error: Error: your settings are undefined. Try reloading the page. If this error persists, try the troubleshooting guide: https://github.com/glacambre/firenvim/blob/master/TROUBLESHOOTING.md

How did you launch the app? I ran it on my development server, and I don't see this error on the console. I also ran the actual webapp and checked the console, but this is not the error that shows up. Could you please provide the steps to reproduce this issue?

I'm getting this in Chrome today when I load the attached csv.
