-In this case, the response from the service contains an error code in the `code` field, a `message`, and a `location` indicating which orchestration module encountered the error. In all error cases, the `module_results` field only contains results for modules that successfully finished. In this example, the `module_results` are empty because the first module in the pipeline encountered the error.
