Environment Information

Very simple test function:

import com.amazonaws.services.lambda.runtime.events.models.s3.S3EventNotification
import io.micronaut.function.aws.MicronautRequestHandler
import io.micronaut.serde.annotation.Serdeable
import org.slf4j.Logger
import org.slf4j.LoggerFactory

@Serdeable
class S3EventHandler : MicronautRequestHandler<S3EventNotification, Void>() {
    private val logger: Logger = LoggerFactory.getLogger(S3EventHandler::class.java)

    override fun execute(input: S3EventNotification): Void? {
        logger.info("Received S3 event: {}", input)
        return null
    }
}

Invoked with example event:

{
    "version": "0",
    "id": "18b9ff9b-ee86-7754-4879-9d047331c10b",
    "detail-type": "Object Created",

    ],

        "bucket": {
            "name": "[randomname](arn:aws:s3:::random-bucket-name-123)"

        },
        "request-id": "2QFRRR8K44ZW7DH3",
        "requester": "1234",
