One of your rewrites in your next.config.js point to a dynamic route that is automatically statically optimized or is a fallback SSG page.
Rewriting to these pages are not yet supported since rewrites are not available client-side and the dynamic route params are unable to be parsed. Support for this may be added in a future release.
For fallback SSG pages you can add the page to the list of prerendered paths.
For static dynamic routes, you will currently need to either rewrite to non-dynamic route or opt the page out of the static optimization with getServerSideProps
