Either wrap the headers() usage in Suspense or mark the route dynamic. The build passes once the dynamic usage is isolated. Applies to: Next.js 13+ app router.
TL;DR
Either wrap the headers() usage in Suspense or mark the route dynamic. The build passes once the dynamic usage is isolated.
The exact error
Dynamic server usage: Page couldn't be rendered statically because it used `headers`
Steps to fix
Find where headers() or cookies() is called in the page the error names
Option A: move that call into a child component wrapped in [Suspense]
Option B: add export const dynamic = 'force-dynamic' to the page if the whole page is dynamic anyway
Rebuild and confirm the prerender error is gone
When this applies
Next.js 13+ app router
A statically prerendered page calls headers(), cookies(), or similar request APIs
When this does NOT apply
Pages router
Routes already marked dynamic
Tool + versions
Next.js 13+ app router
Why it happens
headers() needs a real request, which does not exist during static prerendering. Next.js reports exactly which dynamic API blocked the static render.
Edge cases
searchParams prop in pages has the same effect
Suspense keeps the rest of the page static; force-dynamic makes the whole route dynamic
