We migrated our active process instance from jbpm 5.x to BPM Suite 6 and when we run our process we have the following exception:

Caused by: java.lang.NullPointerException
                at org.drools.persistence.jpa.processinstance.JPAWorkItemManager.internalGetWorkItem(
                at org.drools.persistence.jpa.processinstance.JPAWorkItemManager.completeWorkItem(
