On the wire
Ships with HTTP status 429, carrying "code": "RU-4001" in the response body alongside the human-readable error message. Existing fields are never replaced by the code: it is additive.
Common causes
- An error spike consumed the month's quota.
- A noisy, known error group left unresolved and re-reported on every request.
How to fix it
- Check the Errors dashboard's drop counters to see what consumed the quota.
- Resolve or rate-limit the noisiest issue at the source.
- Upgrade the plan if your normal volume genuinely exceeds the quota; SDKs stop retrying until `resetsAt`.
