Error while deploying AWS Lambda S3 tutorial code

[SandeepKoparde]

I am executing the AWS Lambda S3 tutorial from https://docs.aws.amazon.com/lambda/latest/dg/with-s3-example.html

`I have installed node.js v12 on an ec2 Amazon Linux v2 instance. After following all the instructions in the tutorial, I get the belowerror in the CloudWatch error logs.
The code is available on the tutorial page.

P.S.: The code was running properly when AWS lambda was supporting node.js v4 runtime. Hence I assume the error is due to some change in Syntax.

'{

"errorMessage": "SyntaxError: Unexpected token =>",

}`

This issue is now resolved.
I was using a wrong region in the input.txt.
