I am trying to pull the product list for a magento store using the api key and password, using the code given at https://github.com/magja/magja. However, I am getting only two attributes associated with each product, the rest of them are coming as "null". Also, I get a field as set, which shows that the product attribute set being pulled has an id different from the default attribute set id. Can anyone please explain what is the issue here, and how can we pull all the attributes?
