Likely Causes
  1. MongoDB returned code 103 (NodeNotElectable) while processing this request path.
  2. Server/client state drift caused an unexpected execution-path failure.
  3. A lower-level subsystem raised a non-recoverable error for this request.
How to Fix It
1
Review logs/telemetry for code 103 (NodeNotElectable) and capture the exact command and parameters that triggered it.
2
Collect server/client logs with request IDs and stack context for the failing call.
3
Retry once after confirming system health and dependency availability.
4
Escalate recurring failures with reproducible traces and version/build details.
5
Add monitoring for recurring NodeNotElectable events so future incidents are detected and triaged faster.
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
