Type error: Type '{ params: { <param>: string

}; }' does not satisfy the constraint 'PageProps'.

Cause

the generated .next/types guard checks each page's props against PageProps, whose params is a Promise since 15; a plain-object params type is not assignable.

Fix

risk: low

-export default function Page({ params }: { params: { slug: string } }) {-  const { slug } = params;+export default async function Page({ params }: { params: Promise<{ slug: string }> }) {+  const { slug } = await params;// searchParams is a Promise too; 15.5+ can type props as PageProps<'/blog/[slug]'>

Don’t try

set typescript.ignoreBuildErrors, or exclude .next/types from tsconfig — hides the check while params stays a Promise: the sync read still warns on 15 and is undefined on 16.
