Error when trying to build my vuepress project, used this quickstart guide with npm: https://vuepress.vuejs.org/guide/getting-started.html#manual-installation

I added some pages and everything works fine with:

npm run:dev

But when I want to generated html to docs/src/.vuepress with:

npm run:build

dibTest@0.0.1 build
vuepress build src

This error for me was thrown by the following problem in my config.js

module.exports = {   

...

    sidebar: [
      '/',
      {
        title: 'Quick Start Guide',
        children: [
          '/overview/login.md',
          '/overview/model-list.md',
          '/overview/navigation.md,'
        ]
      }
    ]
  }
}

Note the "," after "navigation.md". For whatever reason this results in the totally unhelpful message above. Must be because it can't find that md file, it then gets an undefined somewhere and tries to access it, rather than detecting this and giving you a helpful message
