Push a feature in a featureSet - Arcade script

Hello,

I would like to add features in a featureSet, I initialize a featureSet and depending on other features I would like to push elements of these features on conditions :

var myFeatureSet = FeatureSet({ layerDefinition: { objectIdField: "FID", geometryType: "esriGeometryPolygon", fields: [ { name: "FID", alias: "FID", type: "esriFieldTypeOid" }, { name: "attributeX", alias: "attributeX", type: "esriFieldTypeDate" }, { name: "attributeY", alias: "attributeY", type: "esriFieldTypeString" } ] }, featureset: { features: [Feature(null, "FID", 1, "attributeX", "Hello World")] } }); var features = FeatureSetByName($map, myLayer,["*"],false) var filteredFeature = Filter(features, 'attributeZ is not null') for(var feat in filteredFeature){ // Push the feat in myFeatureSet }

I tried to do it with Push function but I get Invalid Input ERROR

How can I do it ?

Thanks !

Your code doesn't follow the way that a FeatureSet is established, according to the docs.

https://developers.arcgis.com/arcade/function-reference/featureset_functions/#featureset

Try defining the geometryType, fields, and features, but don't nest them in separate layerDefinition an dfeatureset objects.

var fs_json = { geometryType: "esriGeometryPolygon", fields: [ { name: "FID", alias: "FID", type: "esriFieldTypeOid" }, { name: "attributeX", alias: "attributeX", type: "esriFieldTypeDate" }, { name: "attributeY", alias: "attributeY", type: "esriFieldTypeString" } ], features: [ {attributes: {FID: 1, attributeX: "Hello World"}} ] };

Also, once your FeatureSet is created, you won't be able to push features into it. You'll need to add the features to a dictionary, then create the FeatureSet once all your features have been loaded in.

var features = FeatureSetByName($map, myLayer, ['*'], false) var filteredFeature = Filter(features, 'attributeZ is not null') for ( var feat in feilteredFeature) { Push( fs_json['features'], { attributes: { FID: feat['FID'], attributeX: feat['attributeX'], attributeY: feat['attributeY'] }, geometry: Geometry(feat) } ) } return FeatureSet(fs_json)
