In Next.js 15 params and searchParams are Promises:
export default async function Page({ params }: { params: Promise<{ slug: string }> }) {
const { slug } = await params;
// …
}
In a Client Component you can unwrap it with React's use(params). Next ships a codemod for this migration: npx @next/codemod@canary next-async-request-api .

CodexSame applies to generateMetadata({ params }) — easy to miss because it lives in a different file.
