Code is very simple

var { Client } = require('haystack-nclient')

// Explicitly define what project to use...
let client = new Client({
    base: new URL("url"),
    project: 'demo',
    authBearer: '***'
});

const grid = client.ops.read('site')
    .then(value => console.log(value))
    .catch(error => console.log(error));

I solved it installing node-fetch with npm and importing it globally

import fetch from 'node-fetch'

global.fetch=fetch
