我刚刚从版本 3.10 迁移到 3.11.6。 通过网络界面，我尝试运行基本查询进行测试，但 1000 万年后该查询仍然没有得到解决。
我加载了安道尔的路线图（https://michaelmathieu.net/resources/andorra_data.zip）。
当我运行以下查询时，一切都很好（在不到 1 毫秒的时间内解决）： FOR 路径 IN OUTBOUND K_SHORTEST_PATHS 'points/1' TO 'points/20' 方式限制 1 个返回路径
但是当我添加选项来指定weightAttribute时，它没有响应： FOR 路径 IN OUTBOUND K_SHORTEST_PATHS 'points/1' TO 'points/20' 方式 OPTIONS { WeightAttribute: 'cost', defaultWeight: 1000 } LIMIT 1 RETURN path
以前的版本从未出现过此问题。
这是执行计划：
