Page with dynamic = "error" encountered dynamic data method…

Error message

Page with dynamic = "error" encountered dynamic data method on ${path}.

What it means

Static-export strictness failure: the page segment was configured with dynamic = "error" (fully static), but the render touched a dynamic data API, giving cacheControl.revalidate === 0 with the isDynamicError flag set. next build --output-export therefore aborts for this path instead of producing a non-deterministic static file.

Solutions

1. Remove dynamic = "error" from the page, or remove the dynamic data usage (cookies, headers, etc.) on that path.

When it happens

Trigger: A route with dynamic = "error" uses dynamic data during prerender.

Common situations: cookies()/headers()/fetch-no-store is used in a route forced to static with export const dynamic = 'error'.
