AWS Step function error : There are Amazon States Language errors in your state machine definition. Fix the errors to continue

Question

我是 AWS 步骤函数的新手。尝试创建粘合作业的基本 ETL 流程。状态机定义完成后，我无法看到正在生成的图形，但出现一般错误“您的状态机定义中存在 Amazon States Language 错误。修复错误以继续”， error message 那不允许我继续。

这是代码和图表：

Answer 1

"Comment": "various state types of the Amazon States Language",

第 5 行的这个似乎不正确。 “州”地图不能有“评论”键。删除它，然后尝试。其余配置看起来正确。

如果 Step Function 的类型是 Express，则“.sync”函数将不起作用。尝试将 ARN 更改为

"Resource": "arn:aws:states:::glue:startJobRun"

并且您应该能够保存您的 Step Function。然后您将不得不弄清楚如何设置不同的 Glue 任务。
