| Scene | Yes | 节点创建的场景，决定节点创建在手动节点区域还是数据开发区域。DataworksManualWorkflow只在填写了ContainerId且Container为手动工作流时才能使用。可选值：- DATAWORKS_PROJECT 项目目录- DATAWORKS_MANUAL_WORKFLOW 手动工作流- DATAWORKS_MANUAL_TASK 手动任务 | |

| ContainerId | No | 当你需要将节点创建在一个容器内部时，你需要指定这个参数。该参数为一个容器的唯一标识，这个容器可以是一个Workflow或者一个容器节点。><notice>该参数填写后，FlowSpec中定义的path字段将无效></notice> |
