Invoke shell script in AWS Lambda using node.js

Question

I am new to AWS Lambda. I am trying to invoke a basic "Hello World" shell script from an AWS Lambda function coded in node.js.

run.js file contains the following:

---

#!/bin/bash
echo "Hello, World!" 

---

I have also coded the function by storign it in an index.js file containing the following:

---

var exec = require('child_process').exec;
exports.handler = function(event, context) {
 exec('./run.sh' , function(error, stdout) {
 context.done(error, stdout);
 });
};

---

I have created a zip file containing both files and have uploaded it to AWS Lambda console by creating a new Lambda function and granting it a lambda_basic_execution role.

I was expecting to be able to see the Hello World, have tried variations of this code but so far have been unable to call a shell script from an AWS Lambda function.

Thanks in advance!

Lambda only supports child_process.spawn and child_process.spawnSync. Try changing your call to child_process.exec and that should fix it for you.
