@beltrame here is a sample mouse mask trace which you can use in your pipeline:

{
  "label": "two",
  "vector": [
    {
      "modelID": "dbs.json",
      "shapeID": "dbs.json_46",

        "z": 8.716666667
      }
    },
    {
      "modelID": "dbs.json",

      "nearestVertex": 10544,

    {

    },
    {

      "shapeID": "dbs.json_46",
      "nearestVertex": 10558,
      "point": {

        "y": 1.403390932,
        "z": 8.716666667
      }
    },
    {
      "modelID": "dbs.json",
      "shapeID": "dbs.json_46",
      "nearestVertex": 10558,
      "point": {

        "z": 8.716666667
      }
    }
  ]
}

in this screenshot you can see where to get it out of the user interface for debugging:
