Mongodb – DeprecationWarning: The punycode module is deprecated when running frontend server

I am encountering a DeprecationWarning related to the punycode module when running my frontend server.

The warning message is:

(node:6208) [DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.

This warning appears when I run my frontend server using the command npm run dev.

Here is the relevant portion of the output:

([email protected] dev) next dev
(node:6208) [DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.

I have ensured that all my dependencies are up to date. Despite this, I am still receiving the deprecation warning. The issue seems to be originating from the MongoDB Node.js driver and its dependencies.

Here is the dependency chain causing the issue:

└─┬ [email protected]
  └─┬ [email protected]
    └─┬ [email protected]
      └─┬ [email protected]
        └── [email protected]

I would appreciate any insights or suggestions on how to resolve this warning and update my dependencies accordingly. Thank you in advance for your help.

I have updated my Node.js version to the latest one, and I have also ensured that all dependencies in my project are up to date. Despite these updates, I am still encountering a DeprecationWarning related to the punycode module when running my frontend server.

    I had the same issue with a Nextjs project.

    Try to downgrade your Node version to the latest LTS available. At the moment it’s v20.12.2.

    Hope it helps.

    Fixed

    As Mentioned at NPM

    https://www.npmjs.com/package/punycode#installation

    First

    Throw VSC Search Bar

    You Must Press 3 Points at Right Bottom AND Select ./node_modules IN ‘files to include’ Text Box

    OR Right Click ON node_modules Folder and Select ‘Find On Folder’

    THEN You Can Replace ALL

    require("punycode"); WITH require("punycode/");

    AND All Ones with Single Quotes Too

    require('punycode'); WITH require('punycode/');
