Works with Next.js 16.1.x (downgrading avoids the crash).
Minimal reproduction repo: https://github.com/dulapahv/nextjs-16-2-open-next-cloudflare-loadmanifest-crash
Steps to reproduce
- Deploy a Next.js app to Cloudflare Workers using @opennextjs/cloudflare (OpenNext).
- Ensure wrangler has
nodejs_compatandglobal_fetch_strictly_publicenabled. - Upgrade Next.js to
16.2.0. - Build & deploy.
- Request / -> Worker throws
Unexpected loadManifest(/.next/server/prefetch-hints.json) call!and Cloudflare reports Error 1101.
Expected behavior
The Worker should start and serve requests normally (e.g. GET / returns the page) without throwing a startup exception.
