I'm getting this error when I try to compile with Grunt. I haven't used it much before but I seem to only be getting this error with this project and it works fine for other projects on my server.
Running "jshint:main" (jshint) task Warning: Path must be a string. Received null Use --force to continue.
Aborted due to warnings.

The reporterOutput

Provide an empty string for it in your Gruntfile.js
jshint: {
