Dear Carl,

  I'm sorry, I've no idea what the Cart is. I'm assuming that it is a class which can be instantiated with some dictionary data.

  So you try passing request.data instead of just request to the Cart.

Try to check by printing request.data, it'll be a dict.

FYI you can check the below link, may be you can find the Root cause for your error.
