next.config.js 에러 질문입니다

이번에 next + antd 로 진행하다가 antd customize theme를 써보고싶어져서

https://ant.design/docs/react/customize-theme#Customize-in-webpack

여기에 나와있는대로 웹팩 설정을

const withBundleAnalyzer = require('@next/bundle-analyzer')({
  enabled: process.env.ANALYZE === 'true',
});

module.exports = withBundleAnalyzer({
  compress: true,
  webpack(config, { webpack }) {
    const prod = process.env.NODE_ENV === 'production';
    config.module.rules.push({
      test: /\.less$/,
      use: [
        {
          loader: 'style-loader',
        },
        {
          loader: 'css-loader', // translates CSS into CommonJS
        },
        {
          loader: 'less-loader', // compiles Less to CSS
          options: {
            lessOptions: {
              // If you are using less-loader@5 please spread the lessOptions to options directly
              modifyVars: {
                'primary-color': '#1DA57A',
                'link-color': '#1DA57A',
                'border-radius-base': '2px',
              },
              javascriptEnabled: true,
            },
          },
        },
      ],
    });

    return {
      ...config,
      mode: prod ? 'production' : 'development',
      devtool: prod ? 'hidden-source-map' : 'eval',
      plugins: [...config.plugins, new webpack.ContextReplacementPlugin(/moment[/\\]locale$/, /^\.\/ko$/)],
    };
  },
});

이렇게 기존에서 less 설정만 추가했습니다.

그런데

이런 오류가 뜹니다. custom css configuration 을 해서 built in css support가 중단되었다고하는거 같은데, 해당 링크에 들어가보면 외부 css 관련 플러그인을 사용했을때 뜰 수 있다라고 하는데 그 상황은 아닌거같고요.

혹시 어떻게 해야 웹팩 오류가 안나게 설정을 할 수 있을까요?
