Gulp vs BrowserSync bs.reload not working, how to fix?

Question

gulp.js

the task is started via a lazy function:

'use strict';

const gulp = require('gulp');
const path = require('path');

module.exports = function lazyRequireTask(taskName, config) {

  gulp.task(taskName, function(callback){
    let task = require(path.resolve(`${config.taskPath}/${taskName}`)).call(this, config, taskName);

    return task(callback);
  });

};

task:

'use strict';

const gulp = require('gulp');
const $ = require('gulp-load-plugins')();
const bs = require('browser-sync').create();

module.exports = function(config) {

  return () => {

    return gulp.src(`${config.pugPath}/pages/*.pug`)
      .pipe($.pug({pretty: true}))
      .pipe(gulp.dest(config.outPath))
      .on('end', bs.reload);

  }

};

all tasks are performed according to the same structure.
Well, the bottom line is that bs.reload does not work, there is a suspicion that this is due to a lazy function, help me figure out what the problem is, thanks.
