Does the logic find this 404 link on HEAD?

mui-x/docs/data/date-pickers/date-picker/date-picker.md

Line 53 in eae809f

You can find the documentation in the [Validation page](/react-date-pickers/validation/)

(there is the same 404 on a couple of other pages)

It's weird. The import was fine with yarn link but it does not work now with the monorepo

From what I understand, the file /node_modules/@mui/monorepo/docs/scripts/reportBrokenLinks.js is not able to resolve @mui/markdown

Doing the following modification in the node_module file solves the problem

-const { createRender } = require('@mui/markdown');
+const { createRender } = require('../packages/markdown');

So a solution could be to this modification in the material-ui repository.

Maybe there is another solution, but it's out of my knowledge about package alias

@alexfauquette I have pushed a fix for it, the tricky aspect is that there is a lot happening beyond the scene that is hard to pinpoint the origin of where it starts and where it ends. I hope mui/material-ui#34841 (comment) and my commit bring a bit more clarity on how this fits together. I moved the script execution location to use the babel config of the root that is optimized to run scripts from the mono repo, while the babel config of the docs is designed to build the docs pages.

The CI is still not green but I think a rebase on HEAD would solve the problem, taking #6549 in.
