outstatic: Module not found: Can't resolve 'fs'

I’m trying to add outstatic to an existing project. Which is somewhat working. I can access the editor and also the collection creation is running. Currently, I’m struggling with the following issue:

./node_modules/.pnpm/outstatic@0.0.32-rc_3591a07f5f6bd7e95d5c3230e32ada50/node_modules/outstatic/dist/utils/server.js:1:716
Module not found: Can't resolve 'fs'

Import trace for requested module:
./pages/offers/[slug].jsx

It is the copy of the [slug].tsx page of the blog example, so nothing new or special.

I can get rid of the error if I modify my next.config.js like that:

config.resolve.fallback = {
      ...config.resolve.fallback, 
      fs: false
};

But I get now paths or an empty array in the getStaticPaths method:

export async function getStaticPaths() {
  console.log(getDocumentPaths('offers')) // returns empty array
  return {
    paths: getDocumentPaths('offers'),
    fallback: false
  }
}

I’m pretty stuck cause with the empty array it is not dropping an error, but it is ending up constantly in 404 errors of existing pages.
