getStaticPaths is required for dynamic SSG pages and is miss

Error message

getStaticPaths is required for dynamic SSG pages and is missing for '${pathname}'.

What it means

Guard in renderToHTMLImpl: the page is SSG with a dynamic pathname (contains [param] segments) but exports no getStaticPaths, so Next.js has no way to know which paths to prerender. The combination dynamic+SSG requires getStaticPaths to enumerate params, and its absence is rejected before rendering.

Solutions

1. Add `getStaticPaths` to the dynamic page that uses `getStaticProps`, returning the paths to pre-render and a `fallback` value.
