    Between Jun 19 09:09 and 16:16 UTC, a subset of Vercel Functions using node-fetch@2 may have experienced intermittent invocation errors that surfaced as ERR_STREAM_PREMATURE_CLOSE.

    As part of Node.js June 2026 security releases, we began rolling out new Node.js versions. Those versions contain an upstream regression that breaks response streaming for node-fetch@2, which caused the errors https://github.com/nodejs/node/issues/63989 (opens in new tab)

    We have resolved the issue by reverting to the previous Node.js version. No action is required — affected functions are now operating normally. We will re-land the Node.js upgrade once the upstream issue is fixed.

Archive proof

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.
