Plan price returns None object.

[arpankotecha]

Hello,

I'm running python 2.7.6

I'm trying to loop through all apps and get the price for each addon associated with the app to calculate the total cost of the app. I thought the code below should work but plan.price is None:

for app in conn.apps():
        price_breakdown = []

        addon_list = app.addons()
        for addon in addon_list:
              plan = addon.plan
              price_breakdown.append((
                '{}@{}'.format(app.name, plan.name),
                plan.price.cents))

I get the following trace:

  File "/vagrant/tasks.py", line 129, in check_prices
    plan.price.cents))
AttributeError: 'NoneType' object has no attribute 'cents'

Any thoughts on how I can get the pricing info for each app addon?
Thank you.
