Hi, i am using compas-mixin and when trying to compile it via webpack i am getting following error: (Emitted value instead of an instance of Error) autoprefixer: /Users/vladimir/Projects/affiliates/resources/assets/sass/node_modules/compass-mixins/lib/compass/css3/_images.scss:75:78: Gradient has outdated direction syntax. New syntax is like to leftinstead ofright.
