We recently finished migrating from geometric networks to utility networks for water, wastewater, and storm water. We are on ArcGIS Pro 3.5 and ArcGIS Enterprise 11.5. In ArcGIS Enterprise I published view-only feature services of the utility networks that do not have editing or tracing. Those services do use subtype groups for the symbology. In Map Viewer and Experience Builder the utility network feature services render without issues, but in ArcGIS Field Maps none of those feature services will render.
Field Maps is reporting ArcGIS.MappingError Invalid arcade expression: The Arcade expression requires a later version of Runtime for some of the subtype groups and other subtype groups report ArcGIS.GeodatabaseError Item already exists.
I updated Field Maps to 26.2.1 and the issues remain. If I change the map to use the map services of those view-only services instead, the errors go away and the utility network data shows up in Field Maps. I am not seeing errors in the Field Maps logs even when I turn on verbose logging.
