I have a simple Lambda which is configured to be triggered on s3:ObjectCreated:* event. So when I add an object to s3 bucket my lambda is triggered but lambda handler registered is not invoked. Code:

package main

import (
	"context"
	"fmt"
	"github.com/aws/aws-lambda-go/lambda"
)

func HandlerS3(ctx context.Context, s3Event events.S3Event) error {
	fmt.Println("Handler is called")
	fmt.Println("Handler exiting")
	return nil
}

func main() {
	fmt.Println("Starting Main")
	lambda.Start(HandlerS3)
	fmt.Println("Ending Main")
}

I get following logs

2024-03-13T16:27:58.889+05:30	INIT_START Runtime Version: provided:al2023.v14 Runtime Version ARN: arn:aws:lambda:us-east-1::runtime:xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

It looks like there's an issue with initialization or perhaps a missing component or misconfiguration causing the handler not to trigger. Has anyone encountered a similar situation or can offer insights into why HandlerS3 isn't being invoked as expected?
