## Updates from Vercel
### 2026-06-19 17:54 UTC: resolved
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
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.
