localhost is not resolving to 127.0.0.1

A simple example of

import fetch from "cross-fetch";

fetch("http://localhost:60002/graphql")
  .then(res => {
    if (res.status >= 400) {
      throw new Error("Bad response from server");
    }
    return res.json();
  })
  .then(console.log)
  .catch(console.log);

Returns ECONNREFUSED

FetchError: request to http://localhost:60002/graphql failed, reason: connect ECONNREFUSED ::1:60002
    at ClientRequest.<anonymous> (/Users/dmtrkovalenko/dev/lightsource/www/node_modules/cross-fetch/node_modules/node-fetch/lib/index.js:1491:11)
    at ClientRequest.emit (node:events:513:28)

    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  type: 'system',
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED'
}

But when I change localhost to 127.0.0.1 it works. curl and any other native api's works either with localhost or 127.0.0.1.

This seems to be an issue with local DNS lookup. Check if an entry like this 127.0.0.1 localhost exists on your /etc/hosts file. If the problem persists, please reach out to node-fetch repo to ask for help since cross-fetch just acts as proxy.
