我是 AWS cloudformation 的新手，我的堆栈有问题。我有这些工作，但出了点问题。
假设我有一个 ArtifactBucket 堆栈，其中包含我的 .Net 核心 lambda 和 IAM 用户、角色和 KMS 密钥的 zip 文件。
我有这个主堆栈，它有一个 Creator lambda 将向 SQS Queue 发送消息。处理器功能将接收该消息并将其发送到 SNS，然后 SNS 向我发送电子邮件（请参阅订阅）
这一切都在 AWS 控制台中部署得很好，但我发现当我调用 lambda 时，我需要在收到消息之前多次调用它，并且一些消息丢失了。例如..我会一个接一个发送5条消息，只收到4条消息。
我怀疑它是 lambda 和队列的超时问题，但我正在努力查明它。
您是否发现我在此主模板中遗漏了任何明显的东西，或者队列属性 va lambda 时间值是否存在问题？
