With NextJS Link, How to pass object clientside?

I have a Link component that I'm using and want to pass a JavaScript object to the new page I'm linking to. It seems that I can pass primitives, but not objects.

That is, I want to do something like this below but I get an empty string associated with sessionData (session.id and session.sessionSlug work).

                <Link
                    href={{
                        pathname: "/session", query:
                            {
                                sessionSlug: this.props.session.sessionSlug,
                                sessionId: this.props.session.id,
                                sessionData: this.props.session
                            }
                    }}
                    as={`session/${this.props.session.sessionSlug}`}>
                    <a>{this.props.session.title}</a>
                </Link>

I think you can try to JSON.stringify the object and then JSON.parse it back

Example

pages/index.js

import Link from 'next/link';

export default () => {
  const object = {
    key1: 'value1',
    key2: 'value2'
  };

  return (
    <Link href={{ pathname: '/about', query: { object: JSON.stringify(object) } }}>
      <a>here</a>
    </Link>
  );
};

pages/about.js

import { withRouter } from 'next/router';

function About({ router: { query } }) {
  const object = JSON.parse(query.object);

  return (
    <div>
      about {object.key1} | {object.key2}
    </div>
  );
}

export default withRouter(About);

Hope this helps!
