Javascript API, elevation layer query

ManolisNikolakakis — Sat, 11 Dec 2021 10:32:35 GMT

Hello!
What I want to do is retrieve the elevation of a known point using ArcGIS javascript 4.14. A working example of an an elevation layer query based on the following https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-ElevationLayer.html#queryElevation would be great.

I have a similar piece of code in the following link https://codepen.io/nikolakakis/pen/jObOjEv?editors=1111 I always get the error Failed to query elevation: TypeError: Cannot read property 'wkid' of undefined

I tried with an Elevation layer I uploaded and made it public with the same results.

var layer = new ElevationLayer({
       portalItem: {  // public Elevation layer
           id: "258fc22265f74dfb9a7b2d48338ff2de"
        }
 });‍‍‍‍‍‍‍‍‍‍

Does the

https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-ElevationLayer.html#queryElevation example indeed return an error or do I miss something here?

Thanks in advance.

The syntax to create a Multipoint is incorrect.

// Incorrect
new Multipoint(points)

// Correct
new Multipoint({points: points})‍‍‍‍‍

Once I fixed that, your codepen sample worked.
