this may happen when your graph is broken (not connected) either because of a bad graph topology or because low coherence isolate a portion of the graph.
In the first case you have to re-generate the graph making sure it is connected.
In the second case, you have to change the non-linear weights in order not to isolate any areas. In this second case consider anyway that the “unlucky area” probably will not be consistent with the rest of the analyzed points…

Thank you very much. I changed the non-linear weights and it worked.
