i have this in vue.config.js

css: {
    loaderOptions: {
      less: {
        lessOptions: {
          modifyVars: {
            'primary-color': '#1DA57A',
            'link-color': '#1DA57A',
            'border-radius-base': '2px',
          },
          javascriptEnabled: true,
        },
      },
    },
  },

i've also installed less and less loader.

"less": "^4.1.2",
"less-loader": "^10.2.0",

and here is my babel.config.js

module.exports = {
  presets: ['@vue/cli-plugin-babel/preset'],
  plugins: [['import', { libraryName: 'ant-design-vue', libraryDirectory: 'es', style: true }]],
};

am i doing anything wrong here
