This code defines a webhook handler function that validates incoming requests, retrieves a result based on a specified function, and returns the result as a JSON response.

This code provides a function latestS3 that retrieves the 5 most recently modified files from an S3 bucket, optionally filtering them based on a given pattern. It's designed to be used both as a server-side module and potentially in a client-side environment.

To interact with AWS Lambda using the AWS SDK in JavaScript, you can import the SDK, initialize an AWS Lambda client, and invoke a Lambda function with a custom payload. The AWS Lambda client handles potential errors and success cases by calling context.done in case of an error and context.succeed with the payload in case of a successful function call.
