Not able to save graph in neo4j from spark graphx

I am not able to save the graph generated from spark graphx library into neo4j.

My Vertex RDD looks like:
Array[(org.apache.spark.graphx.VertexId, Double)] = Array((136303622,59.27342560553635)

My Edge RDD looks like:
Array[org.apache.spark.graphx.Edge[String]] = Array(Edge(-1429369390,136303622,1000001)

Getting "zero" saved records in neo4j
scala> Neo4jGraph.saveGraph(sc, graph)
res108: (Long, Long) = (0,0)
