Issue when running flogo build using flogo-web

[Hendrik-Mueller-Overzone]

I've been trying to start the flogo-web project locally. I believe I've followed all the steps in the readme.
When the server starts it executes flogo build -s which exits with code -1 and the following log:

Error in building /.../flogo/flogo-web/dist/local/engines/flogo-web/src

I've attempted to run the tests of the jsexec activity, which pass, so the activity itself can run on my machine.

Is there something I'm missing?

P.S. I hope this is the right place to post this issue, if this is more related to the web-ui, I will gladly post it there
