zhengyingying opened a new issue, #1949:
URL: https://github.com/apache/incubator-hugegraph/issues/1949

   ### 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: memory 
   - OS: CentOS
   - Data Size:  100 vertices, 200 edges 
   
   
   ### Expected & Actual behavior (期望与实际表现)
   
   We execute the query `g.V().outE('el0','el1').has('ep0',true)` in HugeGraph.
   
   ### Expected behavior 
   We expect it returns some edges.
   
   ### Actual behavior
   However, it throws unexpected exceptions.
   `java.util.Arrays$ArrayList cannot be cast to com.baidu.hugegraph.backend.id.Id`
   
   ### Reproduce
   You can reproduce this issue using the following code.
   
   ```connection.getHugespecial().schema().propertyKey("ep0").asBoolean().ifNotExist().create();
               connection.getHugespecial().schema().propertyKey("ep1").asBoolean().ifNotExist().create();
               connection.getHugespecial().schema().propertyKey("vp0").asBoolean().ifNotExist().create();
   
               // vertex
               connection.getHugespecial().schema().vertexLabel("vl0").properties("vp0").nullableKeys("vp0").create();
               connection.getHugespecial().schema().indexLabel("vl0Byvp0").onV("vl0").by("vp0").shard().ifNotExist().create();
   
               // edges
               connection.getHugespecial().schema().edgeLabel("el0").sourceLabel("vl0").targetLabel("vl0").properties("ep0").ifNotExist().create();
               connection.getHugespecial().schema().edgeLabel("el1").sourceLabel("vl0").targetLabel("vl0").properties("ep1").ifNotExist().create();
               connection.getHugespecial().schema().indexLabel("el0Byep0").onE("el0").by("ep0").shard().ifNotExist().create();
               connection.getHugespecial().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));
   
               GremlinManager gremlin = connection.getHugespecial().gremlin();
   
               String query = "g.V().outE('el0','el1').has('ep0',true)";
   
   
   ### Vertex/Edge example (问题点 / 边数据举例)
   
   _No response_
   
   ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)
   
   _No response_
