Can anyone clarify what the proper way is to create a label expression in ArcGIS Pro that displays the area of a polygon, no matter the source of the data?
suggests using (for Python): round(float([AREA]), 1)
or for Arcade: round(number($feature.AREA), 1)
But when I try to validate either of those I get the error 'Invalid field AREA'. This happens for polygon datasets I tried both that were hosted in AGOL and from a Portal using Postgres.
Datasets hosted in AGOL seem to have a 'Shape__Area' field that I can label from, but the dataset from the Portal doesn't have that attribute.
So how can/should I be labeling the dataset from Portal? Is there something *wrong* with the Portal dataset, or feature service, or is there another way to access the geometry of the feature?
