[gatsby-plugin-mdx] cannot find module

Description

I’m trying to add a custom plugin to gatsby-plugin-mdx. I’ve made sure:

• It is located in /plugins/gatsby-remark-normalize-url
• It has a package.json file and index.js
• It is added into gatsby-config.js

{
  "name": "gatsby-remark-normalize-url",
  "description": "Normalize URL's with sindresorhus popular normalize-url lib",
  "version": "1.0.0",
  "dependencies": {
    "normalize-url": "^5.0.0",
    "unist-util-visit": "^2.0.2"
  }
}

const gatsbyPluginMdx = {
  resolve: `gatsby-plugin-mdx`,
  options: {
    gatsbyRemarkPlugins: [
      `gatsby-remark-normalize-url`,
    ],
  }
}

Steps to reproduce

My project: https://github.com/muuvmuuv/portfolio (changes not included but can be added)

1. add a plugin described above into plugins (it shouldn’t do anything)
2. run gatsby develop

Expected result

What should happen?

Actual result

ERROR #11321  PLUGIN

I assume it is pnpm related which I am also running into. Would be great to have the standard gatsby resolve doing the work. Though I have some slightly different issue. I have some base package sharing some code and dependencies, but at the moment I have to add

"@mdx-js/mdx": "~1.5.8",
"@mdx-js/react": "~1.5.8",
"gatsby-plugin-mdx": "^1.1.9",

to every child package to make the mdx rendering work, even though these packages should be taken from the baselib.

This however works:

const gatsbyRemarkPlugins = [
   {
      resolve: require.resolve('./plugins/gatsby-remark-normalize-url'),
   }
]
