AWS SAM-资源之间的循环依赖错误

我遵循了这个 tutorial

我也在努力做到这一点 AWS SAM 为此,我需要定义一个 template.yaml

Failed to create the changeset: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: Circular dependency between resources: [LambdaPerm]

我找不到关于这个的很多信息,所以我正在努力调试。导致此错误的原因是什么?如何解决此问题?这是我的模板配置-
