Reproduction Steps

• pnpx create-payload-app@latest -t blank
• add a UserWorks collection
• add a rewrites configuration in next.config.mjs

import { withPayload } from '@payloadcms/next/withPayload'

/** @type {import('next').NextConfig} */
const nextConfig = {
  // Your Next.js config here
  async rewrites() {
    return [
      {
        source: '/api/v1/ai/user-works/:path*',
        destination: '/api/user-works/:path*',
      },
    ]
  }
}

export default withPayload(nextConfig)

curl http://localhost:3000/api/v1/ai/user-works

{"message":"Route not found \"/api/v1/ai/user-works\""}

• Before 3.16, when I accessed http://localhost:3000/api/v1/ai/user-works, Next.js would rewrite the URL and successfully access /api/user-works.
