An unexpected null value error is sometimes returned during an attribute rule execution on the registered feature service (Oracle and PostgreSQL) when the first Arcade function is on a FeatureSet obtained from a geometry function such as Intersect.

対処法

• Use ArcGIS Pro 3.0.x or older or disable the attribute rule.
• Use the following script:

var parcels = FeatureSetByName($datastore, "databasename.user.featureclassname")

//var filteredParcels = Filter(parcels, "retiredbyrecord IS NULL"); var intersectLayer = Intersects(parcels, $feature);

var parcelCount = Count(intersectLayer) var feat; //replace first by getting the first feature. for (feat in

intersectLayer) console(feat.objectid) if (parcelCount == 1) { return feat.parcelid; } else { if (parcelCount == 0) {

return 'Not on Parcel'; } else { return 'Multiple Parcels'; }; };.
