On the wire
Ships with HTTP status 404, carrying "code": "RU-4006" in the response body alongside the human-readable error message. Existing fields are never replaced by the code: it is additive.
Common causes
- The project or issue was deleted.
- The ID belongs to a different account.
- A typo in the ID.
How to fix it
- List your projects (GET /api/v1/errors/projects) and confirm the ID.
- Confirm the API key belongs to the account that owns the resource.
Still stuck?
Ask support and mention RU-4006: the code pins down the exact refusal path, so you skip the diagnostic back-and-forth.
