Ошибка компиляции LESS через Webpack?

Доброго времени суток!
При расширение класса в LESS выдает ошибку.

.random-planet-info-template(){
        flex-basis: 100%;
        font-size: 1.2rem;
        border-bottom: 1px solid #444444;
    }
    .random-planet-info-name{
        .random-planet-info-template();        
    }

Смотрел в документации - там все так же. В чем проблема?
