部署 AWS Lambda S3 教程代码时出错

Question

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 following error in the CloudWatch error logs.

 { "errorType": "Runtime.UserCodeSyntaxError", "errorMessage": "SyntaxError: Unexpected token =>", "stack": [ "Runtime.UserCodeSyntaxError: SyntaxError: Unexpected token =>", " at _loadUserApp (/var/runtime/UserFunction.js:98:13)", " at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)", " at Object.<anonymous> (/var/runtime/index.js:45:30)", " at Module._compile (internal/modules/cjs/loader.js:778:30)", " at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10)", " at Module.load (internal/modules/cjs/loader.js:653:32)", " at tryModuleLoad (internal/modules/cjs/loader.js:593:12)", " at Function.Module._load (internal/modules/cjs/loader.js:585:3)", " at Function.Module.runMain (internal/modules/cjs/loader.js:831:12)", " at startup (internal/bootstrap/node.js:283:19)" ] }

The code is available on the tutorial page.

PS: 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. I have searched the error string on google but did not find any relevant link.

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