You attempted to share a web layer, web map, or web scene containing a layer that has SHAPE__AREA or SHAPE__LENGTH fields. These field names are reserved for use by map and feature services. Publishing with these field names results in duplicate field names in the web layer. This can cause failures in clients that consume these services.
Hover over the analyzer message. Click the Options button that appears and click Select Layer In The Contents Pane. The layer with the reserved field name is selected.
