Minified es6/luxon.min.js throws 'not a function or not iterable' for valid fromISO()

Describe the bug

TypeError: n is not a function or its return value is not iterable

Note that this runs perfectly fine with the non-minified es6 version.

To Reproduce Please share a minimal code example that triggers the problem:

import { DateTime } from 'https://moment.github.io/luxon/es6/luxon.min.js';
console.log(DateTime.fromISO('2019-01-01T05:00:00.000'));

Actual vs Expected behavior

  • Ensure behaviour is consistent between minified and non-minified version.
  • Ensure no error is thrown on valid fromISO formats (although in this case caused by the minifier).

Desktop (please complete the following information):

  • OS: [e.g. iOS]
  • Browser: Chrome 103
  • Luxon version: latest
  • Your timezone: Europe/Zurich
