A `validation_failed` body also carries `message` (the first failing fields), `hint` (how to fix it, for example that a finding `description` is a TipTap JSON document and not a string) and `details` (field name to messages). content: application/json: schema: $ref: '#/components/schemas/Error' Unauthorized: description: >- Missing or invalid API key. The body names the cause in `code` (for example `ingest_key_not_allowed` when a write-only ingest key is used here) with a `message` and `hint`. content: application/json: schema: $ref: '#/components/schemas/Error' NotFound: description: >- Resource not found in your organization. Also returned when a path id is not a UUID, and `{ "error": "not_found" }` for a path this API does not have.
