Next.js: Page "/blog/[slug]" is missing "generateStaticParams()" so it cannot be used with "output: export" config

A dynamic route can't be statically exported without telling Next.js which paths to generate.

Meaning

With output: 'export' every dynamic segment needs generateStaticParams() returning all params at build time (and dynamicParams = false if you want 404s for others). Or drop output: 'export' and use server rendering.

Common causes

  • output: "export" with dynamic routes
  • generateStaticParams missing or returns empty
  • Data fetch for params failing at build
  • Using server-only features with export
  • Wrong segment names

⚡ Quick fix

  1. export async function generateStaticParams() { return posts.map(p => ({ slug: p.slug })) }
  2. Add export const dynamicParams = false
  3. Remove output: "export" if you need runtime routes

Detailed fix by platform

Next.js

  1. export const dynamicParams = false; export async function generateStaticParams() { return [{ slug: "a" }, { slug: "b" }]; }

How to diagnose

  1. Export — output: export?
  2. Params — Listed?
  3. Alternative — Server hosting?
