My partner test Taiwan i3s 1.8 service like https://i3s.nlsc.gov.tw/building/i3s/SceneServer/layers/5
but ArcGIS Enterprise(Portal) v10.8.1 got issue as following picture:
It works well on:
- ArcGIS Online latest
- ArcGIS API for Javascript v4.23
- ArcGIS Earth v1.15
Should anyone fix this issue? How to do it?
