Parse Error: "import" and "export" may appear only with sourceType: module

Hello everyone, need help with my packages. I am using Gulp and have task for libs (mjs):

import babelify from 'babelify';
import browserify from 'gulp-bro';

export const getLibs = (platform) => {
  return app.src(app.dev(platform).libs, {allowEmpty: true})
    .pipe(browserify({
      transform: [
        babelify.configure({
          presets: ['@babel/env'],
        }),
      ],
    }))
    .pipe(app.rename('libs.min.js'))
    .pipe(app.uglJS())
    .pipe(app.dest(app.build(app.isMobile).scripts));
};

and i have some settings for Swiper (js):

import Swiper from 'swiper/swiper-bundle';

const demoSwiperParams = {
  loop: true,
  slidesPerView: 1,
  speed: 3000,
  effect: 'fade',
  fadeEffect: {
    crossFade: true,
  },
  autoplay: {
    delay: 5000,
  },
};

const demoSwiper = new Swiper('.demo__slider', demoSwiperParams);

Template by pug is:

mixin Demo(content)
  - templateViews = ['desktop', 'mobile'];

  .demo&attributes(attributes)
    .demo__views
      for templateView in templateViews
        picture(class=`demo__${templateView}`)
          source(srcset=`img/themes/views/${templateView}.webp` type='image/webp')
          img(src=`img/themes/views/${templateView}.png` alt='')
    .demo__templates
      for templateView in templateViews
        .swiper.demo__slider(class=`demo__slider--is-${templateView}`)
          ul.swiper-wrapper
            for template, templateIdx in content
              li.swiper-slide
                picture.demo-template.demo__template
                  source(srcset=`img/themes/views/${templateView}/${template.name}.webp` type='image/webp')
                  img(src=`img/themes/views/${templateView}/${template.name}.jpg` alt=template.alt).demo-template__img
                if templateView === 'desktop'
                  p.demo-counter.demo__counter
                    span.demo-counter__text!= `${templateIdx + 1} — ${content.length}`

and i have package.json with type: "module"

I worked with swiper v9.2.2 and it was great, but for now i can't understand what happens and what i need to do. My current version for swiper is 10.3.1 and i have error in my console after task finished well:
Uncaught TypeError: (intermediate value).default is not a constructor

If you have time and more knowledges then me about it - help me please. My regards
