BrowserSync Bitrix not working?

Question

Browsers

Hello. Help tune gulp for Birtix. I connected BrowserSync, but it only opens the site in the browser and that's it. Nothing happens.

import gulp from 'gulp';
import rename from 'gulp-rename';
import sass from 'gulp-sass';
import babel from 'gulp-babel';
import uglify from 'gulp-uglify';
import cleanCSS from 'gulp-clean-css';
import sourcemaps from 'gulp-sourcemaps';
import imagemin from 'gulp-imagemin';
import changed from 'gulp-changed';
import path from 'path';
import autoprefixer from 'gulp-autoprefixer';
var browserSync = require("browser-sync").create();

const base = 'www';
const server = 'btdn.my';
const mytheme = 'bntd';

const paths = {
    styles: {
        src: [
            './local/templates/*/css/**/!(*.min).?(s)css',
            './local/templates/.*/css/**/!(*.min).?(s)css',

            './local/templates/*/components/**/!(*.min).?(s)css',

        ],
        dest: './' + base + '/'
    },
