Multiple Location Column Designator not Working

When working with a dataset with multiple location columns (https://data.detroitmi.gov/Property-Parcels/BSEED-Permits-Issued/n7kb-xdcs) the syntax /socrata/provider/socrataId!columnName no longer appears to work.

Environment:

Most recent build of koop-sample-app and koop-socrata in Ubuntu 14.04 EC2
PostGIS Cache

Calling Path: /socrata/detroitmi/n7kb-xdcs!site_location creates the following log in Node:
