I follow the getting started tutorial, but when I create an email connector and test it, I get the following error:

java.lang.reflect.InvocationTargetException  
org.bonitasoft.engine.bpm.connector.ConnectorExecutionException: USERNAME=install | org.bonitasoft.engine.core.connector.exception.SConnectorException: org.bonitasoft.engine.expression.exception.SExpressionEvaluationException: Groovy script throws an exception of type class org.bonitasoft.engine.identity.UserNotFoundException with message = The technical user is not a usable user

It looks like the `taskAssigneeId` is not a valid user id. Are you sure the connector is defined at the proper place ? It should be in Connectors in section of a Task (not the Pool).

Everything works, when I recreated the tutorial
