Diagnoses

This kind of error often indicates a mismatch of versions between K2 components. In this case, the customer was using K2 blackpearl 4.6.6 in SharePoint 2010 and K2 Studio 4.6.8 (4.12060.1600.0).
 

Resolution

It is not supported to use K2 components of different versions together. Your K2 Studio version will need to match your K2 blackpearl host server version, and your K2 for SharePoint 2010 components version.
Either upgrade your K2 blackpearl environment to 4.6.8, or use K2 Studio 4.6.6.
