Elevation profile not working?

[LefterisKoumis]

Here is a simple elevation profile app but it's not working. After you draw the line, no profile is plotted.

It appears that your webmap does not have a ground elevation layer included (which is required to create the profile).

Add the ground parameter to your web map and it should work:

        const map = new WebMap({
            basemap: "topo-vector",
            ground: "world-elevation"
        });

THanks. I guess things are completely different with API 3.x. I have another app with the elevation profile on JS API 3.x and it is working with streets basemap.
