webpack config not emitting css in build folder

Question

Here is my config for webpack production mode.

const serverConfig = {
  //mode: "production",
  optimization: {
    //minimize: true,
    splitChunks: {
      chunks: "async",
      cacheGroups: {
        commons: {
          test: /[\\/]node_modules[\\/]/,
          name: "vendor",
          chunks: "all",
        },
        // server: {
        //   name: "server",
        //   chunks: "all",
        //   enforce: true,
        // },
        // flightsDesktop: {
        //   name: "flightsDesktop",
        //   test: (m, c, entry = "flightsDesktop") => m.constructor.name === "CssModule" && recursiveIssuer(m) === entry,
        //   chunks: "all",
        //   enforce: true,
        // },
      },
    },
    minimizer: [

}

module.exports = [serverConfig]

I am miising something obvious, what wrong I am doing?
