Symptoms

I'm having an issue porting a k2 development from our sandbox to live. I've used package and deploy and copied the tables and stored procedures over. The issue is that the live version is marking all the input properties for all the methods on the smart object to "Required". This is then breaking a lot of my views that call these methods.
 

Diagnoses

DB permissions issue.
 

Resolution

On the K2 database, set db_owner permissions for K2 service account.
Refreshed service instance in SMO tester.
