async-err-main.cjs

const { fn } = require("./async-err-lib.cjs");

(async () => {
  await fn();
})();

async-err-main.mjs

import { fn } from "./async-err-lib.js";

await fn(); // Error is shown as expected.

async-error-lib.cjs

module.exports.fn = async () => {
  throw new Error("By this error, the process would fail.");
};
