Notes
Production notes from building small web products on Cloudflare: incidents, fixes and setups that actually happened.
- Cloudflare Worker redirect not working? Assets are served first Cloudflare Worker redirect not working on some paths? Static assets answer before your script runs. 2 fixes: run_worker_first, or Single Redirects at the zone.
- Wrangler authentication error 10000 with a per-Worker API token Wrangler authentication error 10000 on a per-Worker Editor token: why verify says active, the first call wrangler makes, and 4 scope gaps that still fail.
- Cloudflare Pages not updating after deploy: the s-maxage trap Cloudflare Pages not updating after deploy, even on pages.dev? Look for s-maxage in your headers. Pages sends max-age=0, and cached HTML can stay 1 week.
