I'm using react-app-rewired and I've recently updated less-loader to the new version (6.0.0). My customize-cra version is 0.9.1.

I'm getting the following error when I run react-app-rewired build:

ValidationError: Invalid options object. Less Loader has been initialized using an options object that does not match the API schema.
options has an unknown property 'source'. These properties are valid:
object { lessOptions?, prependData?, appendData?, sourceMap? }

I've the config-overrides.js file like this:

const { override, fixBabelImports, addLessLoader } = require("customize-cra");

module.exports = override(
  fixBabelImports("import", {
    libraryName: "antd",
    libraryDirectory: "es",
    style: true
  }),
  addLessLoader({
    lessOptions: {
      javascriptEnabled: true,
      modifyVars: {
        "@primary-color": "#030852", // primary color for all components
      }
    }
  })
);

I added the lessOptions object but it didn't solve the problem.
Could you tell me which is the proper way to set addLessLoader options?

Thanks in advance,
