Aws lambda AWS CFN Lambda未向SQS发送所有消息

我是AWS cloudformation的新手，我的堆栈有问题。我让这些工作，但某处出了问题

Asume我有一个ArtifactBucket堆栈，其中包含.Net核心lambdas的zip文件以及IAM用户、角色和KMS密钥

我有一个主堆栈，它有一个

creatorlambda

，它将向

SQS队列发送一条消息。处理器功能将接收该消息并将其发送给SNS，然后SNS将向我发送电子邮件（请参阅订阅）

它在AWS控制台中部署得很好，但我发现，当我调用lambda时，我需要多次调用它，然后才能收到消息，其中一些消息会丢失。例如我将一个接一个地发送5条消息，但只收到4条消息

我怀疑这是lambda和队列上的超时问题，但我正在努力找出原因

您是否发现此主模板中缺少任何明显的内容，或者队列属性和lambda时间值存在问题

   "DelaySeconds" : 0,
   "MessageRetentionPeriod" : 900,
   "ReceiveMessageWaitTimeSeconds" : 5,
   "VisibilityTimeout" : 120,

可能是lambda函数的问题，而不是模板的问题。嘿，谢谢你的回复。据我所知，lambda很好用。创建者lambda只需将消息发送到队列中，我可以看到消息始终在队列中结束。处理器功能然后从队列中获取消息，并将其发送到sns（假定是…）。。。。反复点击AWS控制台中的测试按钮最终会发送消息，但不是全部消息。。两周前我有一个工作的列克发条机，像你一样摆弄着一些东西，然后一切都结束了，我是一个，但现在卡住了…-）
