Hi Mahesh Babu, I had similar problem that your (java.lang.IllegalArgumentException: Messages must never be behind the vertex in ID! Current Message ID: 2 vs. 20 ). In my case the problem was that I tried to send a message to a vertex that was not created. This model of message passing scales better for undirected graphs. I solved this problem by writing a converter that converts directed graphs to undirected graphs.
