I need help with my [login to view URL] app. TASK #1 > the app uses getServerSideProps to generate dynamic routes and the next-sitemap package to generate dynamic sitemaps. since the routes are only generated at request time, the route URLs are not in the generated sitemaps. However, I want the sitemaps to include all the possible route URLs {hundreds of millions of urls} so I can submit the index sitemaps to Google Search Console. There will be 1 index sitemap, 50k child sitemaps, and 50k URLs per child sitemap. since there'd be hundreds of millions of URLs, I want it in such a way that the sitemaps will be generated without too-much space, duplication, or server breakdown. TASK #2 > the app works fine in localhost without any errors. However, each time I visit any route from the deployed version, I constantly get [(Application error: a client-side exception has occurred (see the browser console for more information).] until I refresh more than 5 times for the error to disappear.
