未在 sls deploy 上创建无服务器步进功能状态机

Question

我正在尝试在我的无服务器应用程序中设置步进函数，但是当我将应用程序部署到 aws 时，没有为步进函数创建状态机。这是我的 lambda 文件。我不知道我在这方面做错了什么，但我的设置中肯定有一些东西导致状态机创建失败。

Answer 1

根据提供的 yaml 文件，我认为问题可能是函数定义上的缩进：

functions:
upsertNewCustomerRecord:
    handler: .build/handler.upsertNewCustomerRecord
    iamRoleStatements:

必须替换为：

functions:
  upsertNewCustomerRecord:
    handler: .build/handler.upsertNewCustomerRecord
    iamRoleStatements:

您可以进行此更改并尝试一次吗？

Answer 2

不幸的是，我发现我在构建规范文件中使用了一个反斜杠，这就是导致这种情况发生的原因厌倦了这样做，因为在使用无服务器部署时，您的构建不会失败，您必须深入研究每个文件只是为了弄清楚发生了什么。只是要记住的事情。

Answer 3

在我的例子中，我只是忘了把 End: true 放在 step 函数的最后阶段。也许这会有所帮助。
