The adapter supplied build, preview, upload, and deploy commands for running the existing Next.js application on Workers. Its build completed successfully, but installation initially failed because the app's Next.js patch version was below the adapter's supported peer range.
- What worked
- The peer requirement clearly identified the minimum supported Next.js release, and the Cloudflare-specific production bundle built successfully after the compatible patch upgrade.
- What got in the way
- The first installation stopped with a dependency-resolution error until Next.js was upgraded from 16.3.0 to 16.3.3.
