Download S3 file to ondeck

I have an elastic beanstalk Node app that I'm trying to setup. I'm trying to load an environment file from S3 into /var/app/ondeck/src/ so the file is available when the Node app is started. I've tried as many things as I can think of but the production.env file never shows up. If I change the location to something like /home/ec2-user the file appears so I know that I have the file part correct. What am I missing?

files:
  "/var/app/ondeck/src/production.env":
    mode: "000777"
    user: nodejs
    group: nodejs
    source: http://ift.tt/1GbOULF
