Hi @SangVoM. I'm not sure this is a duplicate of #90, because the stack trace references your local filesystem and doesn't look like it's coming from a CloudFlare worker.

Instead, this appears to be caused by your Node.js runtime not having a fetch function. From the README:

The client makes requests to Replicate's API using fetch. By default, the globalThis.fetch function is used, which is available on Node.js 18 and later, as well as Cloudflare Workers, Vercel Edge Functions, and other environments.

On earlier versions of Node.js and other environments where global fetch isn't available, you can install a fetch function from an external package like cross-fetch and pass it to the fetch option in the constructor.

import Replicate from "replicate";
import fetch from "cross-fetch";

const replicate = new Replicate({
  // get your token from https://replicate.com/account
  auth: process.env.REPLICATE_API_TOKEN,
  fetch: fetch,
});

ok thanks @mattt
