On the wire
Ships with HTTP status 404, carrying "code": "RU-4011" in the response body alongside the human-readable error message. Existing fields are never replaced by the code: it is additive.
Common causes
- The report was submitted before its event's batch finished sending.
- The event's retention window already passed (feedback has no lifetime longer than the event it describes).
- A hand-rolled client sending an eventId that was never the SDK's own minted id.
How to fix it
- Let the SDK's built-in retry run; it is designed for this race.
- Confirm the event actually reached ingest (check the issue's occurrences).
- Use the official SDK's showReportDialog rather than minting your own eventId.

Ask support and mention RU-4011: the code pins down the exact refusal path, so you skip the diagnostic back-and-forth.
