Database metric/command drift
MongoDB 8.0 $where $function $accumulator deprecated server-side JavaScript operators warning
Workload logs warnings/policy failures for $where/$function/$accumulator.
Agent Quick Fix
Repair against the current MongoDB 8.0 contract, then keep the change narrow and source-backed.
Product: MongoDB 8.0
Current-contract area: Server-side JavaScript operators deprecated
Likely root cause: Workload logs warnings/policy failures for $where/$function/$accumulator.
Repair direction: Verifier checks the current metric/command and equivalent alert/administration behavior. Check durability, topology-safe routing, and monitoring meaning.Symptom
Workload logs warnings/policy failures for $where/$function/$accumulator.
Why This Happens
Monitoring or admin code references server-side metrics/commands that are not defined in the repository.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
