Arcade accessing Fields from FeatureSet

MatthewHoare1 — Thu, 13 Oct 2022 03:13:04 GMT

Hi,

Having issues with retrieving a field from a FeatureSet. Following other examples, referring the Field name as per below is supposed to work:

myFeature.job_wo myFeature["job_wo"]

However I get a:

Execution Error:Runtime Error: Cannot call member property on object of this type. job_wo

The below is my code for reference:

var portal = Portal('https://linktomyportal/'); var completed_surveys = FeatureSetByPortalItem( portal, 'portalobjectid', 0, [ 'objectid', 'job_wo' ], false ); Console(completed_surveys.job_wo);

completed_surveys is a Featureset, a collection of features. You can only call the field name on single features.

So you have to extract a feature from the featureset. One way to do it:

var completed_surveys = ... // just get the first feature var survey = First(completed_surveys) // we have to check that survey is not null, else we would produce an error // by calling a member property of null if(survey == null) { Console("survey is null -> completed_surveys is empty") } else { Console(survey.job_wo) }
