Setting the retry policy on a lambda function that has been rolled out using serverless

Question

I have a stack on AWS that I have deployed using serverless. I was about to write code to catch API exceptions (from an external provider) and then put them in another queue when I can across SNS > Topics > Delivery retry policy (https://docs.aws.amazon.com/sns/latest/dg/sns-message-delivery-retries.html) which is exactly what I want. The only problem is I can not find any documentation on how to describe it in my serverless.yml.

Can any give me an example of describing a sns topic retry policy in a serverless.yml file?

You can do so in your function configuration in serverless.yml.

functions:
  asyncHello:
    handler: handler.asyncHello
    maximumEventAge: 7200
    maximumRetryAttempts: 1

Reference: https://www.serverless.com/framework/docs/providers/aws/guide/functions#maximum-event-age-and-maximum-retry-attempts
