Likely Causes
  1. MongoDB returned code 76 (NoReplicationEnabled) while processing this request path.
  2. Replication or sharding state was not aligned with the operation preconditions.
  3. Node role/configuration changed between targeting and execution.
How to Fix It
1
Review logs/telemetry for code 76 (NoReplicationEnabled) and capture the exact command and parameters that triggered it.
2
Refresh topology metadata and retarget the command using current primary/shard ownership.
3
Review replication/sharding events around the timestamp to confirm role transitions.
4
Gate retries on a stable cluster view and avoid stale routing caches.
5
Add monitoring for recurring NoReplicationEnabled events so future incidents are detected and triaged faster.
