    return {
      schema,
      rootValue,

test locally with

const express = require('express');

const app = express();

const { test } = require('./index.bundle.js');

app.use(test);
app.listen(3000, () => {
  console.log('Cool app listening on port 3000!');
});

Put this beside the build folder where your output is.
