Lambda File Write to S3 - amazon-s3

Question

For the past six months I have been downloading the NASA APOD and saving to an S3 bucket using a Lambda function. Up until 12/23/2016 all was working as expected. Now when I check my bucket, the images are there but size 0 bytes. I have included my code below. Does anyone know if there has been a change? Thanks!
var AWS = require("aws-sdk");
var https = require('https');

Answer 1

Found out that NASA APOD API is now using https and not http for images. I had to adjust my code to use https for the image path.
