如何消除TypeError:在sls部署期间无法读取未定义错误的属性“”startsWith“”

Question

目前正在学习无服务器和状态机。当我尝试进行部署时，我得到了错误：TypeError: Cannot read property ‘startsWith’ of undefined。

在下面你可以找到我正在尝试部署的serverless.yml定义。我找不到我犯的错误。

我想要的状态机是非常简单的。我想从decision开始，它将直接指向正确的lambda，取决于输入(本手册中的所有内容，目前都是半手册)。在lambda完成之后(不管是哪一个)将会结束。

这是我在SLS_DEBUG=true之后得到的日志

Answer 1

我的serverless.yml中的第77行有打字错误...应为Resource。
