Cannot read property 'factory' of undefined

What is wrong with this config? it follows the docs but i get:

TypeError: Cannot read property 'factory' of undefined

modules: [
    ['@nuxtjs/feed', {
      path: '/feed.xml', // The route to your feed.
      async create(feed) {
        feed.options = {
          title: 'Some blog RSS Feed',
          link: 'https://someblog.sh/feed.xml',
          description: 'Latest entries on Some Blog'
        }
        const posts = await (axios.get(`${process.env.HEROKU_BACKEND_API_URL}/api/posts`)).data
        posts.forEach(post => {
          feed.addItem({
            title: post.title,
            id: post.slug,
            link: post.slug,
            content: post.content
          })
        })
      },
      cacheTime: 1000 * 60 * 15, // How long should the feed be cached
      type: 'rss2', // Can be: rss2, atom1, json1
    }],
]

Moved to top level config and now it's working. Huh.

Looks like the "inline" module options are handled differently / wrongly

Hello!
We are experimenting the same error, but with the top level config:

• Nuxt Version: 2.14.5
• Nuxt Feed Version: 1.1.0 (we tried 2.0.0, but we run into this issue)

I cannot create a sandbox, because of the project size.

I am sharing the approach we are taking, which is the next best thing I can do.

Any help to understand the issue/ solve it will be greatly appreciated!

Thank you!

const modules = [

  "@nuxtjs/feed" // Side question: We used to have the module in "buildModules". But In your docs it appears in `modules` in all cases. Does it alter the result where to use it when it's only needed during `nuxt generate` ?
