application.js missing - No such file or directory

I checked this and it seems to be working fine.

The barebones.libraries.yml file is referring to a assets/scripts/application.js file which does not exist, since the file is scripts/application.js.

css:
  version: 1.x
  css:
    theme:
      assets/stylesheets/application.css: { minified: false }

js:
  version: 1.x
  js:
    assets/scripts/application.js: { minified: false }
  dependencies:
    - core/jquery
    - core/drupal.ajax
    - core/drupal
    - core/drupalSettings
    - core/jquery.once

assets/stylesheets/application.css and assets/scripts/application.js are compiled with gulp.

As per readme, you have to:

cd .npm
npm install
npm audit fix
gulp
