Gremlin query to get the edge between two vertices

Trying something like this 

List<Edge> result = g.traversal().V().hasLabel("contextlabel").where(__.otherV().hasLabel(labelName)).bothE().toList();

But getting below error org.apache.tinkerpop.gremlin.orientdb.OrientVertex cannot be cast to org.apache.tinkerpop.gremlin.structure.Edge

You're getting that error because V() returns an Vertex and then you try to filter with where() which takes that Vertex as the incoming item in the stream to evaluate. It tries to call otherV() which isn't an available method for a Vertex...that method is meant for an edge. I think that you just have the bothE() in the wrong place and therefore 

g.V().hasLabel("contextlabel").
  bothE().
  where(__.otherV().hasLabel(labelName)).
