Reproducible Demo

[lex111]

Please add the code below to your package.json file and reinstall your deps.

UPD: The building of website should work as before!

  "resolutions": {
    "babel-plugin-dynamic-import-node": "2.3.0"
  }

We will pin the version of this dependency (babel-plugin-dynamic-import-node) in the next release and you (and our new users) will not need to do any manual work, so think about this as a workaround then!

We will consider a solution to use the exact versions of the dependencies used (without caret (^) char) to avoid similar problems in the future!

Sorry about that!

Possibly related to #2244. Not swizzling any components might be a workaround for the issue.

In my case no components were implemented or used, just pure md files.
