How do I send a binary response with AWS Lambda with API Gateway in Node.js? [duplicate]

Question

I'm trying to set up a Lambda and API Gateway that will do a s3.getObject() and output the binary image as a response. Eventually I'd like to pull an image from s3 and resize on the fly instead of saving them back to s3, however I can't seem to get even a simple image to output.

My simple lambda looks like this:

'use strict';

const http = require('http');    

exports.handler = (event, context, callback) => {
    http.get('http://i.stack.imgur.com/PIFN0.jpg', function(res) {
        var body = '';
        res.on('data', function(chunk) {
            // Agregates chunks
            body += chunk;
        });
        res.on('end', function() {
            callback(null, body);
        });
    });    
};

I've set the API Gateway Binary Support to allow 'image/jpeg' and I've tried setting the Content Type in the Method Response and Integration Response.

Method Response:

Integration Response:

I found my answer here: AWS Gateway API base64Decode produces garbled binary?

It requires a CLI command to change a setting that isn't exposed in the AWS Console when you select Lambda Function on the Create Method screen.
