Не работает плагин copy-webpack-plugin при сборке

Решил на новом компьютер склонировать проект, который правильно собирался на старом. Методом проб и ошибок определил, что не срабатывает copy-webpack-plugin при сборке проекта. Все остальное срабатывает.
'app/assets/iframes' не копируется в 'assets/iframes',
'app/assets/locale' не копируется в 'angular/i18n'

Вот код конфига
