The issue is stated in this line of the error:
Caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: Java action was not implemented at oql.actions.ExecuteOQLStatement
When you open the ExecuteOQLStatement java source you'll see that there is a throw exception statement there and nothing else.
I would try to reimport the module and see if this replaces the 'empty' action, if not contact the devleoper of the module as then the provided java action content is misisng from the module.
