'no member defaultdict' being exposed

[steveklabnik]

Trying to run this scenario:

  Scenario: Add a card to a customer                                                                                                                               
    Given I have created a customer

I get this error, with an HTTP 409

Exposing that python stuff seems bad....

Just clarifying that the issue here is that the patch request is malformed as there is no cards object on the the dict, which results in defaultdict being exposed.

Yup, makes sense. I still think this is a bad error message.
