Next.js 15: params should be awaited before using its properties

Error

Error: Route "/fixes/[id]" used `params.id`. `params` should be awaited before using its properties.

Fix

In Next.js 15, params and searchParams in pages, layouts, route handlers and generateMetadata are Promises. Change the signature to async and await it: export default async function Page({ params }) { const { id } = await params; }. Same in route handlers: export async function GET(req, { params }) { const { id } = await params; }
