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?

const genAI = new GoogleGenerativeAI(GEMINI_API_KEY);

const model = genAI.getGenerativeModel({ model: 'gemini-1.5-flash' });

const fetchGeminiResponse = async (message) => {
try {
const prompt = message;

const result = await model.generateContent(prompt);
console.log(result)
const response = result.response;
const text = response.text();

return text;

} catch (error) {
console.log(error)
return 'Sorry, something went wrong.';
}
};
I am using this codebase from Gemini Docs, and my node version is 20.14.0? What will be reason and how to overcome this?
