I have random occurrences of sync function executions not terminating. I added a test log message right before the return res.json(response, 200, headers); (last line of the function).
While logs don't show in the exeucution view in Appwrite Console, because there it only shows the timeout error (see screenshot), they do show in Sentry. And that test log is being sent, which means the function executes until that line before return statement.
Also, the actual database operations of this function get done.
So it basically does everything it should, but somewhere (on the client perhaps?) completion of the function is not detected. And the 30s sync timeout error gets thrown.
Self-hosted setup with server specs:
4 vCPU
8 GB RAM
40 GB Disk local
Function is not heavy, some db operations. If successful, it finishes in approx. 500ms.
TL;DR
Function occasionally does not terminate, throwing a 30s sync timeout error. Logs don't display in Appwrite Console but do in Sentry. Function executes until the last line before `return`, completing the database operations. The issue may be with the client not detecting the function's completion. Server setup is not the cause.
