java.lang.IllegalArgumentException: Vertex constraints only apply to edges

[manish kumar]

        Vertex v1 = graph.vertices("40964208").next();

        Vertex v2 = graph.vertices("40968304").next();

        ((TitanVertex)v1).query().direction(Direction.IN).labels("v1-v2").adjacent(v2).count();

It is throwing

Exception in thread "main" java.lang.IllegalArgumentException: Vertex constraints only apply to edges

What if you try .edgeCount() instead of .count()?

Cheers,

Daniel
