Incident Report

Summary AI Generated

Cloudflare Workers experienced a deployment failure lasting approximately 1.1 hours where Workers using the `nodejs_compat` compatibility flag with a compatibility date of 2026-08-04 or later were incorrectly blocked from deploying. The issue affected both Workers and Workers for Platforms. Cloudflare identified the root cause and implemented a fix, with a workaround of removing the `nodejs_compat` flag available in the interim.

Cloudflare is aware that deploying Workers that the nodejs_compat compatibility flag and a compatibility date on or after 2026-08-04 is being disallowed. This is impacting Workers and Workers for Platforms. We are working on relaxing this assertion. To avoid this error, remove the nodejs_compat compatibility flag from your Worker.
