Hey @otusweb would you mind sharing a sketch file that reproduces this problem?

(sorry for the super late reply, I don't think I got a notification for this)

Thanks @FWMatt for the sketch file. I'm taking a look at this next week.

Hey, the reason you were getting that error is because the font wasn't embedded in your sketch document.

There was also a bug that prevented us from attempting to retrieve the font as a system font, so I've made and merged a patch for that. You should be able to pull from master to get the latest changes and run:

 npm run convert -- /path/to/my/sketch/file.sketch --svg

To export your theme.
