Error when using the K2 smart objects site lists and libraries
 

Diagnoses

Getting the following error:
VALIDATIONThe SharePoint Service V2 broker only supports SharePoint Server 2010 and 2007. Verify the version of SharePoint you’re connecting to, and if it’s SharePoint 2013, use the SharePoint broker instead.Server did not recognize the value of HTTP Header SOAPAction: SourceCode.SharePoint.WebServices/GetAllListsForWebConfigurable



 

Resolution

The K2 for SharePoint was one version behind (4.6.6). Run the blackpearl installer for 4.6.7 on the SharePoint server and it fixed the issue.
