NextJS 13 + Next-MDX-Remote + remarkTwoslash: the request of a dependency is an expression

[LunaticMuch]

I am working on NextJS 13 with App route and next-mdx-remote.

I import Shiki as remark plugin as

import remarkShikiTwoslash from 'remark-shiki-twoslash

Then, when I call the mdx compiler I have

 mdxOptions: {
        remarkPlugins: [
          remarkGfm,
          [
            remarkGithub,
            { repository: 'https://github.com/remarkjs/remark.git' },
          ],
          [remarkShikiTwoslash, { theme: 'dark-plus' }],
        ],
        rehypePlugins: [],
      },

All good, but if I load an MDX file then I get a list of issues:

./node_modules/@typescript/twoslash/node_modules/@typescript/vfs/dist/vfs.cjs.development.js
Critical dependency: the request of a dependency is an expression

This is followed by

- error unhandledRejection: Error: ENOENT: no such file or directory, open 'onig.wasm'

and by this

}

File onig.wasm technically exists in 4 places

./node_modules/shiki-twoslash/node_modules/shiki/dist/onig.wasm
./node_modules/shiki/dist/onig.wasm
./node_modules/vscode-oniguruma/release/onig.wasm
./node_modules/remark-shiki-twoslash/node_modules/shiki/dist/onig.wasm

and the same is for the theme.
Am I possibly missing a configuration item? 🤔
