Describe the bug

I created a simple Next.js application. Inside I have some pages that use SSR (with getServerSideProps) and I have an empty middleware (it just returns NextResponse.next()).

The different pages are pretty simple, just containing a getServerSideProps and printing the content of that on the screen:

import type { InferGetServerSidePropsType } from 'next';
import Link from 'next/link';

type HomeProps = InferGetServerSidePropsType<typeof getServerSideProps>;

const Home = (props: HomeProps) => {
  return (
    <main>
      <div>
        <Link href="/">Home</Link>
        <Link href="/page1">Page 1</Link>
        <Link href="/page2">Page 2</Link>
      </div>

      <h1>Server Side Props</h1>
      <pre>{JSON.stringify(props, null, 2)}</pre>
    </main>
  );
};

export const getServerSideProps = () => {
  return {
    props: {
      page: 'Home',
    },
  };
};
export default Home;

The issue is than randomly when navigating through the links, getServerSideProps return an empty object. That behaviour can be seen on the following video and it appears to happen when we start navigating "too fast":

This only happens when we use next/link, a middleware file and getServerSideProps at the same time.
I created a minimal reproducible example on the following repository: https://github.com/FacundoSpira/amplify-nextlink-middleware-error
And the app is deployed here: https://main.d3g9j0bpx2nsb4.amplifyapp.com/

Expected behavior

The app should navigate correctly, regardless of how many times and how quickly I click on a link.

Reproduction steps

1. Clone the repository: https://github.com/FacundoSpira/amplify-nextlink-middleware-error
2. Deploy it to amplify
3. Navigate to the deployed URL and start navigating between the links. When navigating too quickly getServerSideProps will return an empty object.
