• OS: 8 CPUs, 32 G RAM, ubuntu
• Data Size: 3000 vertices, 5000 edges

Expected & Actual behavior (期望与实际表现)

when i was querying "hasLabel()" after "outE()", it occurred an error if "hasLabel()" contains more than one Label.

Expected

The query is "g.V().outE('edge2','edge3','edge4').hasLabel('edge3','edge2')".It was expected to return edges

Actual behavior

java.lang.IllegalStateException: Illegal key 'LABEL' with more than one value

Example to reproduce

hugegraph.schema().propertyKey("prop1").asText().ifNotExist().create();
hugegraph.schema().propertyKey("prop2").asText().ifNotExist().create();
        hugegraph.schema().indexLabel("locationindex").onE("read1").by("length4").shard().ifNotExist().create();
        hugegraph.schema().edgeLabel("edge1").sourceLabel("vertex1").targetLabel("vertex1").properties("prop1", "prop2").ifNotExist().create();
hugegraph.schema().edgeLabel("edge2").sourceLabel("vertex2").targetLabel("vertex2").properties("prop1", "prop2").ifNotExist().create();
hugegraph.schema().edgeLabel("edge3").sourceLabel("vertex3").targetLabel("vertex3").properties("prop1", "prop2").ifNotExist().create();
hugegraph.schema().edgeLabel("edge4").sourceLabel("vertex4").targetLabel("vertex4").properties("prop1", "prop2").ifNotExist().create();

String query = “g.V().outE('edge2','edge3','edge4').hasLabel('edge3','edge2')”;

However,if the query becomes "g.E().hasLabel('edge3','edge2')", no errors ocur.
