I get this error in the “Live Logs” but not in Grafana.
I’ve noticed other topics with the same issue but no solution.
I’m using node:20-bullseye-slim with ca-certificates installed for libSQL.
Any ideas?
Can you help us help you? When asking questions like this you’ll want to provide as much context as possible, eg your Dockerfile, error trace, etc…
I will do my best without disclosing my full codebase.
I have no error in the backend, no error on the frontend, the error only happens in “Live Logs” from Fly.io dashboard, it doesn’t show up in Grafana from “Log Search” link on Fly.io dashboard.
My Dockerfile is literally the default one from the Docker generated one by Fly tooling (link), the only exception is adding ca-certificate (see Issue).
I add it in both build and base step.
Stack trace error: As explained, this is only showing up in Fly.io “Live Logs”.
It’s a Remix app using LibSQL (completely remote on Turso), everything works very well, just this annoying random logs.
There is no pattern regarding requests / time / etc. It shows up randomly in the logs, like currently my last 2 lines are this error with no request.
Can you share the Dockerfile? The link you provider is the template.

I don’t know if this will resolve the issue, but you install ca-certificates but you never update them: update-ca-certificates
Also, you should lock down your node version, as minor and patch updates may contain breaking changes (nodejs had one last month)
Thanks for the suggestion, unfortunately it did not work.
Maybe use node v22.6.0?
