Convex deploy fails on Node 20+ Linux: upgrade convex past 1.25.2
If convex deploy fails on Node 20+ with fetch failed and retry loops while older Node versions work, upgrade the convex npm package to 1.25.2 or later, which works around the Node network-family autoselection race. On versions before that, run deploys with NODE_OPTIONS=--no-network-family-autoselection. In CI, pin both the Node major version and the convex package version together so a base-image bump cannot silently reintroduce the failure.
Context: GitHub issue get-convex/convex-js#52 (closed, 13 comments): convex deploy failed on Linux with Node 20+ with fetch failed and repeated request retries during schema validation, while Node 18/19 worked. The maintainer traced it to a Node.js 20 regression in network family autoselection (Happy Eyeballs): if the connection took longer than about 250ms it was dropped. The fix shipped in convex@1.25.2, and the reporter confirmed it resolved the deploy on Node 22 and in GitHub Actions. Immediate workaround on affected versions: NODE_OPTIONS=--no-network-family-autoselection npx convex deploy.Maintainer review
