My Lines layer is not displayed in my 3d scene

[DanielLeón81]

I have a layer of lines that I have to visualize in my application created with the ArcGIS api for JavaScript but when I load it, it is not visualized. I tried to publish it from arcgis pro as a scene Layer but it did not allow me. Do you have any recommendation to apply to solve this problem?

I attach a view of the layer from arcgis pro and I will leave a link to the layer.

I will leave a link to the layer.

Could you share a link to the problematic web layer?

Here is the layer I want to include in the application as a 3d line:

Similar / same problem as https://community.esri.com/t5/arcgis-javascript-maps-sdk-ideas/why-all-the-entities-of-the-layer-are...

Lines have z values of 0, and therefore sink under ground.
(Lines are actually partially visible for me, but clearly intersect with terrain surface: https://www.arcgis.com/home/webscene/viewer.html?url=https://services.arcgis.com/qovwaCdMoEzUUFzS/ArcGIS/rest/services/RoutesFly/FeatureServer/0)

-> Try changing elevationMode to `on the ground`.
