Less loader failing to retrieve file content from node module

Bug report

Packages affected

• [ ] sandpack-client
• [x] sandpack-react

Description of the problem

I am trying to import a package that itself import a less file from a different package. They are both private packages pulled from a proxy via Verdaccio

The first package is a react component library importing a less file

import "./myLessFile.less"

and this less file imports less variables from another package (for example purposes @org/myPackage)

@import '~@org/myPackage';

When the less loader tries to load content from @import "~@org/myPackage" the content is empty:

What steps can we take to reproduce the problem?

Unfortunately, as these packages are private and I can't find a component library using less loader I'm not sure how to share a reproducible example. I know that this makes my issue really hard to investigate. If you have any idea what I could do to pin point the issue please let me know
