Unexpected Token { in browser console on fresh new yeoman+fountainJS projects

See original GitHub issue

Issue details

I’m using Yeoman with FountainJS to generate a new project. As soon as it finish assembling it, I simply run the classic npm run serve. It finishes without errors but then I get this error in chrome browser console:

Uncaught SyntaxError: Unexpected token }

The error is reported to be generated from browser-sync-client.js?v=2.23.5:89. My doubt is if the issue is actually in browserSync or in something else built by fountainJS package. I tried building an angularJS (simple landing page) and angular (todo mcv) project but the error persist with both cases even if they’re different framework/languages/source.

Steps to reproduce/test case

Install Yeoman
Add fountainJS
Generate a project (keep it simple, I didn’t continuous integration support for example)
run npm run serve
Open the browser to the newly running webserver
Open the console
