AWS Lambda:The provided execution role does not have permissions to call DescribeNetworkInterfaces on EC2

Question

Today I have a new AWS Lambda question, and can\'t find anywhere in Google.

I new a Lambda function, there is no question. But when I input any code in this function[eg.

Answer 1

It is definitely a strange error, but are you sure the example code you added is the one you're using in your lambda?

Because in your code, you are trying to log something in your lambda after returning control via the callback. In other words, first you told your lambda that you're done. Next, while it is busy shutting down and returning your results, you try to do some logging...

So first, I'd try this:

exports.handler = (event, context, callback) => {
    console.log('this is a test');
    // do stuff
    callback(null, 'Hello from Lambda'); // only do a callback *after* you've run all your code
};

And see if that fixes the problem.
