Attempts to add a scene layer to a scene in ArcGIS Online Scene Viewer fail, and the following error is returned:
Error: <Layer_Name> - <Layer_Name> cannot be added Scene Layer has an incompatible vertical coordinate system. The height model (ellipsoidal) must match that of the scene (gravity-related-height).
This is an expected behavior when an unsupported Z coordinate system is used to create the feature. This error can be related to the following warning when publishing the feature layer to ArcGIS Online, ArcGIS Pro: 24090: Ellipsoidal vertical coordinate systems may draw incorrectly.
Change the coordinate system of the scene in ArcGIS Pro before publishing to ArcGIS Online.
Note: When clicking Analyze before publishing, ensure the 24090 warning is not returned.
