Sinks method return [null]

[idellien]

Hi, thanks for your great work!
I have an issue with sinks method. Here is my graph in JSON view

{
  "options": {
    "directed": true,
    "multigraph": false,
    "compound": false
  },
  "nodes": [
    {
      "v": "20269"
    },
    {
      "v": "42556"
    },
    {
      "v": "43435"
    },
    {
      "v": "56487"
    },
    {
      "v": "87863"
    },
    {
      "v": "90135"
    },
    {
      "v": "94830"
    },
    {
      "v": "95646"
    },
    {
      "v": "null"
    }
  ],
  "edges": [
    {
      "v": "95646",
      "w": "null"
    },
    {
      "v": "43435",
      "w": "87863"
    },
    {
      "v": "94830",
      "w": "56487"
    },
    {
      "v": "56487",
      "w": "20269"
    },
    {
      "v": "20269",
      "w": "42556"
    },
    {
      "v": "42556",
      "w": "null"
    },
    {
      "v": "87863",
      "w": "90135"
    },
    {
      "v": "87863",
      "w": "94830"
    },
    {
      "v": "90135",
      "w": "20269"
    },
    {
      "v": "90135",
      "w": "56487"
    }
  ]
}

I have pushed 8 nodes, but graph create a new one with id null, do you know why this can happen?
And the main issue
graph.sinks() ---> [null]
but from graph you can find that there should be 2 nodes [95646, 42556]

Your example is incorrect. The output of graph.sinks() is correct. The only sink is the node with the label null. The node 95646 is not a sink because it has an outgoing edge to the node labelled null. The node 42556 is not a sink because it also has an outgoing edge to the node labelled null.

Are you treating null nodes somehow specially? Can you provide the code you are running instead of the JSON?

@dionyziz Thanks for answer, by this time hardly to remember problem details. Code was already changed. I think this issue can be closed.
