It looks like this package is using an old version of @whatwg-node/fetch. After upgrading to Node v22.0.0, I see warnings about punycode being deprecated. The source is graphql-codegen.

Describe the solution you'd like

Upgrade @whatwg-node/fetch to the latest version.

Describe alternatives you've considered

Have you tried to update your lockfile?

This issue doesn't have anything to do with the lockfile.

Very simple reproduction steps:

1. Make an empty directory
2. run node --version and confirm node is version 22.0.0 or newer
3. run npm init -y to create package.json
4. run npm install -D @graphql-codegen/cli @graphql-codegen/typescript @graphql-codegen/typescript-resolvers
5. run npx graphql-code-generator init

The punycode warning appears immediately:

npx graphql-code-generator init
(node:2916) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

This same warning appears when running graphql-codegen
