I’m trying to set the properties “Retry attempts” and “Maximum age of record” on an AWS Lambda EventSourceMapping to a DynamoDB Stream - via serverless.yml ([serverless.com](http://serverless.com) framework). When the stack is deployed, they keep the default values, and not the values I set. Help? Thanks

My code:

```auto
name-of-serverless-function
  handler: src/functions/my.handler
    events:
    - stream:
        type: dynamodb
        batchSize: 1
        maximumRetryAttempts: 2
        maximumRecordAgeInSeconds: 8
        arn: properWorkingARN

```

Current serverless framework (1.71.1) handles maximumRetryAttempts. It doesn’t handle maximumRecordAgeInSeconds, though. For that, you’d have to put an `extensions` section in your `serverless.yml`. Something like:

```auto
functions:
  myfunc:
    handler: src/functions/my.handler
      events:
      - stream:
          type: dynamodb
          batchSize: 1
          maximumRetryAttempts: 2
          maximumRecordAgeInSeconds: 8
          arn: 'arn:aws:kinesis:xx-fake-region:123456789012:MyStream'

extensions:
  MyfuncEventSourceMappingKinesisMyStream:
    Properties:
      MaximumRecordAgeInSeconds: 60 # 60 s in the minimum value for this property

```
