How to selected a custom DEM to be used in the custom Elevation Profile Widget?

[FeixRui]

Hi. I would like to use the  Elevation profile widget https://community.esri.com/t5/web-appbuilder-custom-widgets/elevation-profile-widget-version-2-17-9-...

in a map with my custom DEM data. However this widget uses the default ESRI DEM data, Someone has some suggestion how to fix it? Thanks

Were you ever able to figure out how to use a custom DEM?

Unfortunately no. My published DEM image sits on Portal Enterprise, and it is not working, since the Default source is in ArcGIS Online. I tried to follow the steps that the widget developer recommended (he asks to publish a geoprocessing service), but it failed (the guide was made for ArcMap in 2014). I could not find any update for that. Read that and you can have an idea of the issue: https://community.esri.com/t5/arcgis-enterprise-portal/using-web-app-templates-elevation-profile-por...
