Return type {Object | String} crashes ESLint JSdoc

[bugwelle]

Thank you very much for this useful plugin. It appears, that the latest patch version (38.1.1) introduced a bug.
I'll do my best to describe it below. A minimal example as well as demo-repository is attached.

Expected behavior

ESLint (jsdoc plugin) reports issues, if any.

Actual behavior

ESLint (jsdoc plugin) crashes with an internal error TypeError: Cannot read properties of undefined (reading 'type').

If I use @return {Object | String}, it crashes. @return {object | String} works.

Full stack:

❯ npm run lint

> eslint-issue@1.0.0 lint
> eslint index.js


Oops! Something went wrong! :(

ESLint: 8.12.0

TypeError: Cannot read properties of undefined (reading 'type')

Everything worked in 38.1.0, but 38.1.1 crashes. Seems to be related to #860

For an example, see below.

ESLint Config

{
  "root": true,
  "plugins": ["jsdoc"],
  "extends": ["plugin:jsdoc/recommended"]
}

ESLint sample

'use strict';

/**
 *
 * @param {Object} param
 * @return {Object | String}
 */
function abc(param) {
  if (param.a)
    return {};
  return 'abc';
}

Furthermore, I have created a minimal example here: https://github.com/bugwelle/eslint-issue

Environment

That was fast! I didn't expect this be fixed within 15min after reporting. That is amazing! 💯 🎉

Thank you very much, @brettz9 !

Sure, my pleasure. 🙏 I did a little more tightening just now in 38.1.3 though your particular example was fixed in 38.1.2.
