zx: [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in package.json

Nbb, a ClojureScript interpreter for Node.js uses dynamic import to load libraries. To resolve which JS file to load, it uses code like the following:

import { createRequire } from 'module';

const req = createRequire(import.meta.url);

console.log(req.resolve('zx'));

This code worked in zx 5.3.0 but stopped working in 6.0.7 with the following error:

$ node script.mjs
path
node:internal/errors:465
    ErrorCaptureStackTrace(err);
    ^
