connect.reload() завершается ошибкой после задачи jekyll в файле gulpfile.js

Question

Это gulpfile.js код должен следить за моими файлами и преобразовывать их при изменении. Кажется, все работает хорошо, кроме connect.reload()после джекилла Помогите мне в решении этой проблемы, а также советы по возможной оптимизации кода в целом.

var gulp = require('gulp'),
    less     = require('gulp-less'),
    plumber  = require('gulp-plumber'),
    connect  = require('gulp-connect');

function jekyll() {
  var through = require('through2');
  return through.obj(function (file, enc, cb) {
    var spawn = require('win-spawn');
    spawn('jekyll', ['build', '--config', file.path.split('\\').slice(-1)], {
      stdio: 'inherit'
    }).on('close', function() {
      cb();
    });
  });
}

gulp.task('connect', connect.server({
  root: ['../deployment'],
  port: 8888,
  livereload: true,
}));

gulp.task('less', function() {
  return gulp.src('./less/bootstrap/bootstrap.less')
    .pipe(plumber())
    .pipe(less({
      paths: [ './less/bootstrap/*.less' ]
    }))
    .pipe(gulp.dest('./css'))
    .pipe(connect.reload());
});

gulp.task('jekyll',function() {
  return gulp.src('./_config.yml')
    .pipe(jekyll())
    .pipe(connect.reload());
});

gulp.task('watch', ['connect'], function(){
  gulp.watch('./less/bootstrap/*.less', ['less']);
  gulp.watch([
    './_layouts/*.html',
    './_includes/*.html',
    './_posts/*.*',
    './css/*.*',
    './index.html'],
  ['jekyll']);
});

gulp.task('default', ['connect', 'watch']);
