Empty Mdx nodes

[baldh]

Hello, apologies if this question is not appropriate.
I'm using gatsby-source-google-docs and gatsby-plugin-mdx. If I'm getting it correctly, for every document in the specified folder in gatsby-source-google-docs options, an mdx node is generated. However, no Mdx node is generated in my case.

The config looks like following:

import { fileURLToPath } from 'url';

const __dirname = path.dirname(fileURLToPath(import.meta.url));

const config = {
  jsxRuntime: 'automatic',
  jsxImportSource: 'react',
  siteMetadata: {
    title: `Example`,
    description: `:)`,
    image: `https://source.unsplash.com/ePpaQC2c1xA`,
    siteUrl: `https://www.example.com`,
  },
  plugins: [
    {
      resolve: 'gatsby-source-google-docs',
      options: {
        folder: '1tup0oo06vp8V8wvJ5LZKqRBgVkVVdYCe',
      },
    },
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `content`,
        path: `${__dirname}/content`,
      },
    },
    {
      resolve: `gatsby-plugin-mdx`,
      options: {
        extensions: [`.md`, `.mdx`],
      },
    },
  ],
};

export default config;

Graphql query

  allMdx {
    nodes {
      id
    }
  }
}```
returning this output
```{
  "data": {
    "allMdx": {
      "nodes": []
    }
  },
  "extensions": {}
}```

Is there anything wrong with the config? Your help will be highly appreciated. Thank you in advanced.

You don't need gatsby-source-filesystem plugin.

Could you try remove extensions: ['.md', '.mdx'] option?
