Likely Causes
  1. MongoDB returned code 97 (NoProjectionFound) while processing this request path.
  2. An internal runtime condition interrupted normal command execution.
  3. Server/client state drift caused an unexpected execution-path failure.
How to Fix It
1
Review logs/telemetry for code 97 (NoProjectionFound) and capture the exact command and parameters that triggered it.
2
Escalate recurring failures with reproducible traces and version/build details.
3
Collect server/client logs with request IDs and stack context for the failing call.
4
Retry once after confirming system health and dependency availability.
5
Add monitoring for recurring NoProjectionFound 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.
