----------------------------------

             Summary: Transform option gives wrong result since it transform degree edge too.
                 Key: S2GRAPH-38
                 URL: https://issues.apache.org/jira/browse/S2GRAPH-38
             Project: S2Graph
          Issue Type: Bug
            Reporter: DOYUNG YOON
            Assignee: DOYUNG YOON
            Priority: Minor


There is no check if edge is {{degreeEdge}} or normal {{indexEdge}} when we transform fetched edges using EdgeTransformer on QueryParam. 

I think it is necessary to skip {{Graph.convertEdges}} when edge is {{degreeEdge}}

ex) there is no edges exist from srcVertex "a". if we query with "transform": [["from"]], then now query result has one edge {"from": "a", "to": "a"}. this is an edge that transformed from degreeEdge {"from": "a", "to": "0"}. 

I think using special target vertex id "0" in degree edge yield this problem and buggy, but for now transforming edge based on queryParam's EdgeTransformer can skip transform if considering edge is {{degreeEdge}}.
