Browser side rendering

Describe the bug
I followed the "quick start" guide and am attempting to load a spec in the browser and getting a "path.join is not a function". Is only server-side rendering supported? I didn't see anything to that effect in the quickstart guide.

Expected behavior
To be able to use the RedocStandalone in an existing react application

I might be missing something, but from the docs it seems that all I need are the packages installed, and then can use the RedocStandalone react component to render the docs in the browser without utilizing the server side redering abilites. If this is not correct, what am I missing?

import { RedocStandalone } from 'redoc';

export const ApiSpec = (definition: any) => (
  <RedocStandalone
    spec={definition}
    options={{
      theme: { colors: { primary: { main: '#dd5522' } } },
    }}
  />
);

Start by reproducing the quick-start setup with RedocStandalone in an existing React application and trace the reported "path.join is not a function" error. Review the 13-comment discussion for the intended outcome; done should be either browser rendering working or the quick-start documentation clearly stating the supported rendering mode.
