How to eliminate TypeError: Cannot read property ‘startsWith’ of undefined error during sls deployment

Question

目前正在学习无服务器和状态机。当我尝试进行部署时出现错误：TypeError: Cannot read property ‘startsWith’ of undefined.

您可以在下面找到我正在尝试部署的 serverless.yml 定义。我无法发现我犯的错误。

我想要的状态机真的很基础很简单。我想从决定开始，这将直接纠正 lambda，取决于输入（所有本手册，现在是半手册）。 lambda 完成后（无论是哪一个）都会结束。

这是我在SLS_DEBUG=true:

我的 serverless.yml 中的第 77 行有错字...应该是 Resource。
