Forge Data Visualization not working on Revit rooms [ITA] - data-visualization

Question

I followed the tutorials from the Forge Data Visualization extension documentation: https://forge.autodesk.com/en/docs/dataviz/v1/developers_guide/quickstart/ on a Revit file. I used the generateMasterViews option to translate the model and I can see the Rooms on the viewer, however I have problems coloring the surfaces of the floors: it seems that the ModelStructureInfo has no rooms.
The result of the ModelStructureInfo on the viewer.model is:
t {model: d, rooms: null}
Here is my code, I added the ITA localized versions of Rooms as 3rd parameter ("Locali"):
const dataVizExtn = await this.viewer.loadExtension("Autodesk.DataVisualization");
// Model Structure Info
let viewerDocument = this.viewer.model.getDocumentNode().getDocument();
const aecModelData = await viewerDocument.downloadAecModelData();
let levelsExt;
if (aecModelData) {
levelsExt = await viewer.loadExtension("Autodesk.AEC.LevelsExtension", {
doNotCreateUI: true
});
}
// get FloorInfo
const floorData = levelsExt.floorSelector.floorData;
const floor = floorData[2];
levelsExt.floorSelector.selectFloor(floor.index, true);
const model = this.viewer.model;
const structureInfo = new Autodesk.DataVisualization.Core.ModelStructureInfo(model);
let levelRoomsMap = await structureInfo.getLevelRoomsMap();
let rooms = levelRoomsMap.getRoomsOnLevel("2 - P2", false);
// Generates `SurfaceShadingData` after assigning each device to a room (Rooms--> Locali).
const shadingData = await structureInfo.generateSurfaceShadingData(devices, undefined, "Locali");
// Use the resulting shading data to generate heatmap from.
await dataVizExtn.setupSurfaceShading(model, shadingData, {
type: "PlanarHeatmap",
placePosition: "min",
usingSlicing: true,
});
// Register a few color stops for sensor values in range [0.0, 1.0]
const sensorType = "Temperature";
const sensorColors = [0x0000ff, 0x00ff00, 0xffff00, 0xff0000];
dataVizExtn.registerSurfaceShadingColors(sensorType, sensorColors);
// Function that provides a [0,1] value for the planar heatmap
function getSensorValue(surfaceShadingPoint, sensorType, pointData) {
const { x, y } = pointData;
const sensorValue = computeSensorValue(x, y);
return clamp(sensorValue, 0.0, 1.0);
}
const sensorType = "Temperature";
dataVizExtn.renderSurfaceShading(floor.name, sensorType, getSensorValue);
How can I solve this issue? Is there something else to do when using a different localization?
Here is a snapshot of what I get from the console:

Answer 1

Which viewer version you're using? There was an issue causing ModelStructureInfo cannot produce the correct LevelRoomsMap, but it gets fixed now. Please use v7.43.0 and try again. Here is the snapshot of my test:
BTW, if you see t {model: d, rooms: null} while constructing the ModelStructureInfo, it's alright, since the room data will be produced after you called ModelStructureInfo#getLevelRoomsMap or ModelStructureInfo#getRoomList.
