amazon-web-services - AWS DataPipeline 通过 Cloudformation 引发错误 'type is not defined in fields'

Question

我正在尝试部署 Export DynamoDB Table to S3通过 Cloudformation 生成模板，但从 Cloudformation 获取 type is not Defined in fields 错误。我的所有 PipelineObjects 都有一个 Key，其值为 type，但 Default ParameterObject 除外，因此我不确定错误指的是什么。有人对这里可能发生的事情有任何想法吗？谢谢!

事实证明，Default pipelineObject 需要 type 为 Default
