I don't have any immediate pointers as to what's going wrong here, but my first guess is in the node.js versions; I'm still on Node 12 LTS.

[andrewstart]

It looks like updating uglify-js fixes the issue - recent patch notes do mention some work around handing Typescript's enums.

I've updated the devDependencies. Thank you for contributing!
