Error: Dynamic server usage: Route /x couldn't be rendered statically because it used `cookies`
Next.js tried to statically render a route that reads request-specific data (cookies, headers, searchParams).
Dynamic server usagecouldn't be rendered statically because it used Meaning
During next build, routes are prerendered by default. Using cookies(), headers() or uncached fetches forces dynamic rendering; Next.js reports it when it can’t render statically.
Common causes
- cookies()/headers() in a page meant to be static
- fetch with cache: 'no-store' in a static route
- Catching the dynamic usage error in try/catch
⚡ Quick fix
- Mark the route dynamic: export const dynamic = 'force-dynamic'
- Move request-specific logic to client components or route handlers
- Don’t swallow Next.js internal errors in try/catch
Detailed fix by platform
React
export const dynamic = 'force-dynamic';
How to diagnose
- Route — Which route and API?
- Intent — Should it be static?
