Report #102883

[bug\_fix] Error: cookies\(\) or headers\(\) requires a dynamic request context, but none was available.

Either add \`export const dynamic = 'force-dynamic'\` to the layout or page, or use \`cookies\(\)\` and \`headers\(\)\` only in server components that are already dynamic \(e.g., a route handler or a page that does not have static generation\).

Journey Context:
I built a Next.js app with a server component that called \`cookies\(\)\` to get a user token. During build, the error appeared. I had assumed that server components always have access to request data, but they can be statically rendered at build time, in which case there is no request context. The static optimizer cached the page, but \`cookies\(\)\` needs a real request. After reading the Next.js docs on dynamic rendering, I learned the fix is to force dynamic rendering using \`export const dynamic = 'force-dynamic'\` at the top of the page or layout. Alternatively, I could use \`import \{ cookies \} from 'next/headers'\` only inside an async server component that is not statically optimizable \(like a route handler\). The root cause is that statically rendered pages have no HTTP request at build time. The fix works by telling Next.js to treat the page as dynamic, ensuring that \`cookies\(\)\` and \`headers\(\)\` are called during a real request.
