Question

我一直在尝试使用lambda支持的自定义资源。我尝试使用自定义资源触发Lambda函数。在堆栈创建时，自定义资源在CREATE_IN_PROGRESS上挂起，但是我能够获取电子邮件，并且在尝试删除堆栈时，它仍然在DELETE_IN_PROGRESS上。

现在我有五个堆栈挂在DELETE_IN_PROGRESS上。创建自定义资源在哪里？

你的模板正在挂起，因为lambda没有正确执行回调到cloudformation。

在你的SES回调中，你首先不会在出现错误的情况下发送回调，但除此之外，你首先用＆＃34; context.succeed（event）终止Lambda;＆＃34;然后调用＆＃34; response.send（event，context，response.SUCCESS）;＆＃34;。

为了正确实现，您只需要调用response.send函数。在该函数中，将调用callback.succeed。

您可以使用此网站上的示例作为参考。 aws lambda for cloudformation
