App fails to load in Heroku

[larsen161]

I just attempted to simply deploy to Heroku from the Github page and faced the following issue right away.

I created my API key in APIs & Services, restricted the key to Street View Static API leaving application restrictions to None. I grabbed my Street View Static API secret from: https://console.cloud.google.com/google/maps-apis/credentials

Looks like libgl1 isn't in your Aptfile.

Are you on the most current branch? I cannot replicate this.
