If you get this random error on 'Mondays' (yes... on Mondays :-)) likely it is related to a Webpack bug (that has to do with a message asking for donation only on Mondays ).

TypeError: process.getuid is not a function  (cli.js:356:43)

See details here:
webpack/webpack-cli#962

Changing the timezone to a country already on Tuesday or upgrading to"webpack-cli": "^3.3.5" fixed the issue. Obviously the solution is the latter to make the starter work..

PS: clueless why this didn't crash last Monday but the timezone change and the new version did the trick. Probably the starter should use a more recent webpack-cli version.
