Can't run build

[MatiMenich]

Hi, I've just forked this repo (great work btw) and I'm running npm run build after installing everything and im getting the following error:

28 11 2017 17:42:11.819:WARN [reporter]: SourceMap position not found for trace: undefined
HeadlessChrome 0.0.0 (Mac OS X 10.12.6) ERROR
  Uncaught ReferenceError: __ALLOW_POSTMESSAGE_POPUP__ is not defined
  at test/test.js:1665

Please help :)

Full output:
