OLD VERSION (using fs.readFile)
===============================================
With this function I did NOT get a full async stacktrace. Example:
FileNotFoundError: File not found: c3ba0f23b58a5c645b7f3e803b1ba5af42d8d2f9262b029d2718a89709ba0b03 [objects]

How to get stacktraces from errors from asynchronous functions (node.js and all browsers - simple)
// @flow
'use strict';
// Needed to create a _really_ asynchronous function. A fake asynchronous function (returning
// "Promise.reject()" right away, for example) actually creates a stacktrace.
const wait = delay => new Promise(resolve => setTimeout(() => resolve(), delay));
// Some deeply nested (in the actual call hierarchy) asynchronous function that throws an error.
const fnError = async () => {
await wait(1);
