Я пытаюсь получить данные из БД, используя alpakka Slick .Я настроил базу данных Oracle в свойствах.

При загрузке сеанса из SlickSession я получаю исключение ниже

Ниже приведен мой файл свойств для конфигурации базы данных. 

# Load using SlickSession.forConfig("slick-oracle")
slick-oracle {
  profile="slick.jdbc.OracleProfile$"
  db {
    dataSourceClass="slick.jdbc.DriverDataSource"
    connectionTestQuery=“SELECT 1 FROM DUAL”
    properties={
      driver="oracle.jdbc.OracleDriver"
      url="jdbc:oracle:thin:@//localhost:1524/test"
      user=testUser
      password="testPass"
    } 
  }
}

Состояния исключений, связанных с проблемой подключения,но это не тот случай.В SQL Developer я использовал ту же конфигурацию, которая работает так же, как и в других java-программах Я использовал ту же конфигурацию.Это работает для других программ.

Пожалуйста, кто-нибудь может помочь?
