[Debian-pan-maintainers] Bug#1102558: jupyterlab: runtime fails with ReferenceError: require is not defined

[PICCA Frederic-Emmanuel]

If I remove the external commonjs crypto, the error comes from here


ERROR in node:crypto
Module build failed: UnhandledSchemeError: Reading from "node:crypto" is not handled by plugins (Unhandled scheme).
Webpack supports "data:" and "file:" URIs by default.
You may need an additional plugin to handle "node:" URIs.

And indeed the firt line of 

/usr/share/nodejs/@rjsf/core/lib/index.js

containes this:

import { webcrypto } from 'node:crypto';

This file is part of the package

dpkg -S /usr/share/nodejs/@rjsf/core/lib/index.js
node-rjsf: /usr/share/nodejs/@rjsf/core/lib/index.js

is it the real issue ?
