exports.handler = async () => {
  return { test: 1}
}

Recently, AWS launched Lambda Destinations, that makes it possible to route asynchronous function results to a destination resource that can be either SQS, SNS, another Lambda function or EventBridge. With DLQs you can handle asynchronous failure situations and catch the failing events, but with Destinations you can actually get more detailed information on function execution in both success and failure, such as code exception stack traces. Although, Destinations and DLQs can be used together and at the same time, AWS suggests Destinations should be considered a more preferred solution.
