Magento 1.9 Rest API - Fetch Product Data with Custom Attribute

Question

I am using module (in Magento 1.9.3.10) that extends the default Mage/Product model by adding a new attribute named Status with a corresponding file named Status.php residing in Package\ModuleName\Model\Catalog\Product\Attribute. The Status attribute also extends Mage_Eav_Model_Entity_Attribute_Source_Abstract.

If I try to access the REST API for products on either my development and production servers (with the required OAuth parameters), i.e http://localhost/magento/api/rest/products causes a 500 internal error whiles every other rest endpoint do not fail.

How can I include the custom attribute in the REST API without causing 500 internal errors?

NB: I am using an OAuth consumer which has been verified and I am able to fetch products IFF the custom module is uninstalled

I was able to find the cause of the problem. An observer was set on catalog_product_collection_load_before. It called a function that tries to access the the details of the user through Mage::getSingleton('admin/session')->getUser(). Unfortunately, this returns null when it is a REST call.
