error object with code and message fields. The possible error codes are:| Code | Meaning | Action |

invalid_argument | Invalid request input (unsupported duration, invalid image/video, prompt too long, conflicting modes, or content blocked by moderation) | Fix the request parameters or input media, then submit a new request |
permission_denied | The API key does not have permission for the requested operation | Verify API key permissions |
failed_precondition | The operation is not available for the selected model or settings | Change the model, mode, resolution, or other settings |
service_unavailable | Video generation is temporarily overloaded | Retry the request later |
internal_error | Internal service failure | Retry the request; if persistent, contact support with the request_id |
Authentication errors, missing models, and rate limits are returned synchronously as standard API errors before a video job is created.
