Autodesk aps-iot issue: heatmap failed, sprite is not bounding with rooms

I just start learning about the forge viewer, and currently trying to create data-visualization in forge viewer.
I cloned the Autodesk Data Visualization service, aps-iot-extensions-demo-master,I followed previous similar question I solved this issue by setting const APS_MODEL_VIEW = ” and changing getDefaultGeometry() to getDefaultGeometry(true).

I just replaced APS_CLIENT_ID, APS_CLIENT_SECRET, APS_MODEL_URN and APS_MODEL_VIEW; the URN and GUID.
I used the same model racbasicsampleproject.rvt, i couldn’t find rooms in model structure with the below command:

const structureInfo = new Autodesk.DataVisualization.Core.ModelStructureInfo(model);

Then i found a blog to get the rooms information from the revit file i followed the instruction and create a job to generateMasterViews.

{
  "input": {
    "urn": "<>"
  },
  "output": {
    "formats": [
      {
        "type": "svf",
        "views": [
          "2d",
          "3d"
        ],
        "advanced":{
          "generateMasterViews":true
        }
      }
    ]
  }
}

But i’m still not getting the rooms in model structure
However, the heatmap is not visualized in the Web and there is no error existing in the console.

How can i get the rooms structure from the revit model from racbasicsampleproject.rvt model.
How can i ensure that sprites are bound with the rooms,
How can i get bound of the rooms, so i can show heatmap.
i have not changed the sensor detail in io.moked.js.
