Description of the bug:

I am building an extension for Raycast, while using the Gemini API, however getting the following error when I am just following the Quickstart guide. I saw the previous same issues but my node version is already more than 18.

ReferenceError: fetch is not defined

Sounds similar to https://github.com/google-gemini/generative-ai-js/issues/173. Can you answer these questions?

This error will occur if there's no fetch available in the global namespace. If you're using Node 20, this shouldn't be a problem. Are you able to run a simple node script in that same environment that just calls fetch() (on any valid url)? Are you using any kind of framework or library that polyfills or overwrites fetch?
