我已将我的工作流程场景分解为 2 个单独WorkflowTemplates的 . outer-template将只定义步骤并inner-template保留job将启动所需容器的定义，以及所有其他花哨的东西。现在，当我提交请求时request.yaml，它确实将参数传递message给外部和内部模板并失败并出现以下错误：

在步骤中将参数传递给模板时，您必须显式设置参数值。

在outer-templateWorkflowTemplate 中，您调用inner-template了两次。在每种情况下，您都指定了一半的message论点。您还必须value为每个参数设置 。

您应该设置value: "{{inputs.parameters.message}}"和。这将从.step-1step-2messageouter-template.HelloWorld
