markdown-to-vue-loaderでmdファイルがimportできない

markdownファイルをvueコンポーネント内で読み込みたいのですが、パースに失敗してしまっているようで動きません。
以下のエラーの解決方法を教えてもらえますでしょうか。

You may need an appropriate loader to handle this file type.

vue.config.jsやpackage.json、サンプルのmarkdownファイルは以下になります。

vue.config.js

module.exports = {
  chainWebpack: config => {
    config.module
      .rule('md')
      .test(/\.md$/)
      .use('vue-loader')
      .loader('markdown-to-vue-loader')
      .options({
        exportSource: true,
      })
      .end();
  },
  devServer: {
    watchOptions: {
      ignored: /node_modules/,
    },
  },
};
