Start by reproducing a Next.js 13.4.13 Pages Router app deployed to Amplify Hosting in eu-north-1, following the five listed refreshes in an incognito window. Compare the intermittent empty pageProps and missing getServerSideProps data with the deployment's available build settings and logs; done means the data is returned consistently.
