Gulp-uglify and fotorama?

Question

JavaScript

gulpfile.js :

var gulp           = require('gulp'),
    gutil          = require('gulp-util' ),
    sass           = require('gulp-sass'),
    browserSync    = require('browser-sync'),
    concat         = require('gulp-concat'),
    uglify         = require('gulp-uglify'),
    cleanCSS       = require('gulp-clean-css'),
    rename         = require('gulp-rename'),
    del            = require('del'),
    imagemin       = require('gulp-imagemin'),
    cache          = require('gulp-cache'),
    autoprefixer   = require('gulp-autoprefixer'),
    ftp            = require('vinyl-ftp'),
    notify         = require("gulp-notify");

// Скрипты проекта
gulp.task('js', function() {
  return gulp.src([
    'assets/app/libs/jquery/dist/jquery.min.js',
    'assets/app/libs/fotorama/fotorama.js',
    'assets/app/libs/mmenu/dist/jquery.mmenu.min.js',
    'assets/app/libs/owl/owl.carousel.min.js',
    'assets/app/libs/magnific-popup/dist/jquery.magnific-popup.min.js',
    'assets/app/libs/animate/animate-css.js',
    'assets/app/libs/flatpickr/dist/flatpickr.min.js',
    'assets/app/libs/flatpickr/dist/l10n/ru.js',
    'assets/app/libs/jquery.maskedinput/dist/jquery.maskedinput.min.js',
    'assets/app/js/common.js', // Всегда в конце
    ])
  .pipe(concat('scripts.min.js'))
  .pipe(uglify())
  .pipe(gulp.dest('assets/app/js'))
  .pipe(browserSync.reload({stream: true}));
});

When connecting fotorama, an error is generated that the createElement function was not found in the final minification file. If you do not minify JS, then everything works fine. What to do?

Why not take the already minified one?
