Warning - node.children.flatMap and problem to get $content

[kriss145]

Hello,

I've created a fresh project with the latest Nuxt.js and @nuxt/content module.

1. When I starting I have the warning:
   Could not parse ./content/index.md: node.children.flatMap(...) is not a function or its return value is not iterable

2. I'm trying to get a content from index.md but it's error. I don't know why.
   Example of code:

  async asyncData({ $content, params, error }) {
    const slug = params.slug || 'index'
    const page = await $content(slug)
      .fetch()
      .catch(() => {
        error({ statusCode: 404, message: 'Page not found' })
      })

    return {
      page,
    }
  },

Do you know what is happening with it?

Version

@nuxt/content: ^1.11.1
nuxt: ^2.14.12

What is Expected?

I would get a content from index.md

What is actually happening?

I can't get any content from index.md

What is your node version?

node 10.20.0 - Nuxt.js wanted this version
