AWS Step function error ：状态机定义中存在 Amazon States Language 错误修复错误以继续

如何解决AWS Step function error ：状态机定义中存在 Amazon States Language 错误修复错误以继续

我是 AWS 步骤函数的新手。 尝试创建粘合作业的基本 ETL 流程。完成状态机定义后，我可以看到正在生成的图形，但出现一般错误“状态机定义中存在亚马逊状态语言错误。修复错误以继续”， error message 这不允许我继续。

这是代码和图表：

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，“.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，您必须弄清楚如何设置不同的 Glue 任务。
