Your style uses 4 loaders, and postcss is applied first in order. This error is thrown by postcss because it cannot parse this syntax, not less.

So it should be enough to swap the positions of less-loader and postcss-loader.
I don’t understand. Is this how .a() is written in less?? It should be .a{}
