Next.js Daily: Quiet Failures and Cache Contracts
Today's activity centers on turning silent or misleading server errors into correct HTTP status codes, and on tightening the caching system's contracts around streams, private data, and error messaging. A parallel thread of Turbopack reliability fixes addresses HMR reconnection and build-time concurrency.

Good morning. It's September 1st, and today's Next.js activity has a clear throughline: making error handling honest.
Three PRs from dennytosp attack the same root problem from different angles. PR 98103 fixes cases where broken URLs or wrong HTTP methods return a 500 instead of the correct 400 or 405, because the app router had no fallback error page to render. PR 98105 gives malformed Server Action bodies a 400 instead of a 500,…
Caching got similar scrutiny. Aurora Scharff's PR 94300 rewrites the "use cache" error messages into one shared factory — shorter, consistent, and always linking to docs, replacing error text that had grown inconsistent over time. Alongside that, unstubbable's PR 98039 corrects the documented contract for custom…
On the build side, Will Binns-Smith shipped two Turbopack reliability fixes: PR 96566 makes server hot-reload demand-driven instead of eager, and PR 97966 makes the dev client detect a stale HMR connection and reload rather than silently drift out of sync. Separately, PR 98093 targets a scaling bottleneck in…
Also worth noting: eps1lon's 97954 and 97949 re-enable AVIF image optimization on 15.5.x and 16.3.x behind a runtime version guard, closing…
