当我遇到以下错误时，我正在尝试 neo4j graphaware 预计算功能：

我已将必要的罐子放在 /plugin 目录中。以下是jar文件：
graphaware-reco-3.1.4.49.11.jar graphaware-server-community-all-3.1.4.49.jar my-reco.jar
如文档中所述，我还在 neo4j.conf 中添加了必要的配置。我查看了图形感知代码。
当给出错误输出时会出现一条"Could not start GraphAware Runtime because the database..."消息database.isAvailable(5*60*1000)（在我的情况下是立即），这使我得出结论，我的数据库正在关闭。我看到了日志以获得确切的信息。
以下是日志：

有人可以帮我吗？
