title: AWS SNS is not invoking lambda function when both are created using Cloudformation template
body: <p>I have created lambda and SNS using cloudformation. Here first lambda is invoking a SNS which has a subscription of another lambda. Here SNS is supposed to invoke alias of lambda. In SNS topic lambda ARN is showing as subscriber but in lambda it is not added as trigger. There is not a single invocation log of the lambda invoked from SNS. So is this problem about some kind of permission or else ? need help... </p>
