Replace Deprecated Punycode Module in OpenAI Package

  1. 1

    Update OpenAI Package

    Check for the latest version of the `openai` package that may have resolved the dependency on the deprecated `punycode` module. Update your package to the latest version using npm.

    bash
    npm install openai@latest
  2. 2

    Modify Import Statements

    If the latest version still uses `punycode`, consider modifying your import statements to use an alternative library that is compatible with Node.js 21. You can use the `punycode/` package from npm instead.

    javascript
    import punycode from 'punycode/';
