TypeError: Cannot convert undefined or null to object at Function.keys

[michtio]

I'm trying creating a task to check my js, but every time I call the function it fails:

my code (just stripped it down to the essentials):

var gulp = require('gulp');
var jscs = require('gulp-jscs');

gulp.task('lintjs', function(){
  gulp.src(['./app/js/**/*.js','./.tmp/js/**/*.js','./gulpfile.js','./tools/**/*.js'])
    .pipe(jscs())
    .pipe(jscs.reporter())
});

the error:

[11:25:13] Starting 'lintjs'...
[11:25:14] 'lintjs' errored after 305 ms

apparently a .jscsrc file is required. Maybe write that down in your docs, it's obligatory to create such a file? With a .jscsrc file I don't get any errors.

Hey @mike-lighthouse,
I have exactly the same issue it doesn't seems working even with the .jscsrc file.
Where did you put your file?

[radek11]

put the .jscsrc file where the gulpfile.js is (or I think where gulp can find it)
