I am trying to use @SqlResultMapping with one of my queries:

query = this
     .getEntityManager()
     .createNativeQuery(
       "SELECT DISTINCT proj.*, mess.trigger_date"
         + "FROM ci_project as proj LEFT JOIN ci_project_message as mess "
         + "on proj.message_no = mess.message_no "
         + "WHERE proj.survey_contact = :userId",
       "surveyManagement").setParameter("userId", userId);

I made a SqlResultMapping for this query:

@SqlResultSetMapping(name = "surveyManagement", entities = {
    @EntityResult(entityClass = CiProject.class),
    @EntityResult(entityClass = CiProjectMessage.class, discriminatorColumn = "MESSAGE_NO", fields = { @FieldResult(name = "triggerDate", column = "trigger_date") }) })

I am getting the following error when I try to execute this query:

I am new to using SqlResultMapping annotation. Any advice or point in the right direction will be greatly appreciated!
