name | string | The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id} . |
done | boolean | If the value is false , it means the operation is still in progress. If true , the operation is completed, and either error or response is available. |
error | object | The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC. Each Status message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the API Design Guide. |
metadata | object | Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any. |
response | object | The normal response of the operation in case of success. If the original method returns no data on success, such as Delete , the response is google.protobuf.Empty . If the original method is standard Get /Create /Update , the response should be the resource. For other methods, the response should have the type XxxResponse , where Xxx is the original method name. For example, if the original method name is TakeSnapshot() , the inferred response type is TakeSnapshotResponse . |
