Getting Deprecation Warning while running the project

[HaroldObasi]

I am running a python websocket server with ocpp, its running on port 9000

i followed the installation docs for this project but when i run the project with yarn start ws:://0.0.0.0:9000/, i get this :

[info] Starting charger simulator { csURL: 'ws:://0.0.0.0:9000/', connectorId: 1, chargerId: 'test', idTag: '12345678' }

Charger simulator starting (node:73090) [DEP0040] DeprecationWarning: Thepunycodemodule is deprecated. Please use a userland alternative instead. (Use node --trace-deprecation ... to show where the warning was created)

not sure if it's my server, or if maybe it is from the deprecation warning

Hey @HaroldObasi !

This warning is caused by using classic Yarn in NodeJS 21+

To fix, downgrade NodeJS to the previous version or wait until they release a fix for Yarn, as described in yarnpkg/yarn#9005.

It's also should be safe to just ignore this warning.
