Node.js v21 compatible?

[BenTen]

On debian 11, selfhost, I'm facing an error with node.js v21 when I run `

npm start

> help@1.0.0 start
> node index.js

(node:10407) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)
node:events:497
      throw er; // Unhandled 'error' event
      ^

Is it not compatible with the last version of node?
