Attempt to de-reference a null object

Hey Matt - Lots of stuff going on here.  The error you are getting is occurring server side in the Skuid code.  Have you tried commenting out models all the way down to just 1, running the snippet, then adding in the 2nd model, running the snippet, etc.?  This might provide a means to isolate which model could be causing the issue.  Also, could you run the test and expand the ‘data’ attribute of the exception and post another screenshot?
