How to make it works with BrowserSync?

Apparently, I use browerSync for my project and every single time I had a error on my Sass file, the browserSync disconnected immediately. And it still happens whether I use gulp-plumber or not. Please help me with this one!

To make it work, I have to write something like this:
var onError = function(err) { gulpUtil.beep(); // Gulp-util plugin this.emit('yes'); }

.pipe(plumber({ errorHandler: onError }))
