Hello, I'm having an error when I try to complete a human task through Activiti Explorer.
I'm starting the workflow through my own APP, and then use Activiti Explorer to claim and complete the Task.

Here is my error

Cause: org.apache.ibatis.exceptions.PersistenceException:
### Error querying database.  Cause: org.activiti.engine.ActivitiException: unknown variable type name jpa-entity
### The error may involve org.activiti.engine.impl.persistence.entity.VariableInstanceEntity.selectVariablesByExecutionId-Inline
### The error occurred while setting parameters
### Cause: org.activiti.engine.ActivitiException: unknown variable type name jpa-entity
