Too Many Filesystem Checks

The router performed too many filesystem lookups while trying to resolve the request path, usually caused by a very large number of rewrite rules or a deeply recursive routing configuration. Returned with HTTP 502; simplify the rewrites in vercel.json or the framework's routing config.
