- `message` (GenerationErrorMessage, required) — A message describing the error.
- `statusCode` (double, required) — The type of error that occurred.
- `errorCode` (string, optional) — Stable, machine-readable error code (e.g. project_not_found, voice_not_found, concurrency_limit_reached).

- `suggestion` (string, optional) — A suggested fix an agent can act on.

- `requestId` (string, optional) — Present on unexpected 500 responses. Include it when contacting support so the failing request can be located directly.
- `generationId` (string, optional) — Original generation ID when available for an uncertain keyed submission. Poll this ID; do not create another action to bypass IDEMPOTENCY_OUTCOME_UNKNOWN.
- `dialogueEditSection` (DialogueEditRetimeFailureSection, optional) — For dialogue_edit_removal_too_large: the section to change, when it can be identified. Create a new dialogue edit preview before submitting again.
