Error when call onesky.locales()

[voznik]

when I try to get separate translations files as in your 2nd example

'use strict';
// gulp
var gulp = require('gulp');
var onesky = require('gulp-onesky');
var oneskyOptions = {
  publicKey: 'myKey',
  secretKey: 'myKey',
  projectId: '184430',
  sourceFile: 'translation_en.json'
};
gulp.task('translate', function () {
  onesky(oneskyOptions)
  .pipe(gulp.dest('app/i18n'));
});


gulp.task('translate-more', function () {
  onesky.locales(oneskyOptions)
  .pipe(gulp.dest('app/i18n'));
});

I get Error:

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));
    ^
