The code it is having issue with is this:

r = requests.get(link)
myfile = r.json()

which is confusing because it works fine locally.

Answer 1

This had a really stupid solution. I had to import requests in my requirements.txt. That was why it wasn't recognizing json() (since it was a requests function).

My requirements.txt now looks like:

Flask==0.9
Jinja2==2.6
Werkzeug==0.8.3
gunicorn==0.17.2
requests==2.2.1
