zhengyingying opened a new issue, #1969: URL: https://github.com/apache/incubator-hugegraph/issues/1969
### Bug Type (问题类型) _No response_ ### Before submit - [X] 我已经确认现有的 [Issues](https://github.com/hugegraph/hugegraph/issues) 与 [FAQ](https://hugegraph.github.io/hugegraph-doc/guides/faq.html) 中没有相同 / 重复问题 ### Environment (环境信息) - Server Version: v0.12.0 - Backend: inmemory - OS: xx CPUs, xx G RAM, Centos 7.x - Data Size: xx vertices, xx edges <!-- (like 1000W 点, 9000W 边) --> ### Expected & Actual behavior (期望与实际表现) The reproduce code as follows. ``` /** create schema */ // property schema.propertyKey("ep0").asBoolean().ifNotExist().create(); schema.propertyKey("ep1").asBoolean().ifNotExist().create(); schema.propertyKey("vp0").asBoolean().ifNotExist().create(); // vertex schema.vertexLabel("vl0").properties("vp0").nullableKeys("vp0").create(); schema.indexLabel("vl0Byvp0").onV("vl0").by("vp0").shard().ifNotExist().create(); // edges schema.edgeLabel("el0").sourceLabel("vl0").targetLabel("vl0").properties("ep0").ifNotExist().create(); schema.edgeLabel("el1").sourceLabel("vl0").targetLabel("vl0").properties("ep1").ifNotExist().create(); schema.indexLabel("el0Byep0").onE("el0").by("ep0").shard().ifNotExist().create(); schema.indexLabel("el1Byep0").onE("el1").by("ep1").shard().ifNotExist().create(); /** create graph data */ Vertex vertex1 = new Vertex("vl0").property("vp0", true); Vertex vertex2 = new Vertex("vl0").property("vp0", false); Vertex vertex3 = new Vertex("vl0").property("vp0", true); graph.addVertices(Arrays.asList(vertex1, vertex2, vertex3)); Edge edge1 = new Edge("el0").source(vertex1).target(vertex2).property("ep0", true); Edge edge2 = new Edge("el1").source(vertex1).target(vertex3).property("ep1", false); graph.addEdges(Arrays.asList(edge1, edge2)); ``` We create three vertices and two edges. When we execute the query `g.V().outE('el0','el1').hasLabel('el0')`, we expect the edge `edge1` can be obtained. However, an exception `Illegal key 'LABEL' with more than one value` was thrown. We find that a closed issue (https://github.com/apache/incubator-hugegraph/issues/1735) reported the same bug, and it seems to be fixed. Unfortunately, we still find the same bug. Maybe it deserves further investigation? ### Vertex/Edge example (问题点 / 边数据举例) _No response_ ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构) _No response_ -- This is an automated message from the Apache Git Service.
