Fixes intermittent Fauna FetchError: socket hang up on requests to db.fauna.com from the Node driver. Use this when every few thousand requests one fails with no pattern on a long-lived server. Not for consistent connection failures or auth errors.
TL;DR: if the Fauna Node driver intermittently fails with FetchError: request to https://db.fauna.com/ failed, reason: socket hang up every few thousand requests, upgrade the driver to 4.1.1 or newer. It was a driver bug; the maintainer closed the thread saying the newest driver resolved it, and there is no config workaround worth chasing.
FetchError: request to https://db.fauna.com/ failed, reason: socket hang up
Steps
Upgrade the driver to at least 4.1.1.
Run your normal request volume.
Expected: the intermittent hang-ups stop. Success check: thousands of requests complete without the FetchError.
When to use this
Intermittent socket hang up with no pattern, from a long-lived server (not a lambda thaw issue).
Driver 4.0.3 or similar older version.
When NOT to use this
Every request fails; check network and auth.
You are already on a current driver and still see it; report it fresh.
Compatibility
Fauna Node driver 4.1.1+ (thread closed April 2021).
Variant phrasings
"fauna socket hang up node driver"
"faunadb-js intermittent FetchError"
Root cause
A driver-side bug dropped connections intermittently under sustained request volume.
Edge cases
Retry logic can mask this but not fix it; upgrade instead.
