Arcade expression returns FeatureSet but "Unable to execute Arcade script" displays in indicator

Hi,

I'm trying to create an indicator in ArcGIS Dashboards that display the percentage of features with a specific attribute value using an Arcade expression. I can see the correct result in the create new expression window, but once i click "done", the indicator displays: "Unable to execute arcade script"

For context:

I have a hosted feature layer with a field called "estado".
I want to calculate the percentage of those features where estado = 'Rechazada IPEEM/Archivo'.
Running the script in the create new expression window returns the FeatureSet correctly.
Log window doesn't display any warnings or errors.

Try something like this, I think you've mostly got it:

// Point to Portal var p = Portal('https://maps.arcgis.com/') // Create featureset var fs = FeatureSetByPortalItem(p, '5c798c532ad5448ea9e973de8ddf8076', 2, ['State'], false) var total = Count(fs) var michigan = Count(Filter(fs, "State = 'Michigan'")) // Calculate percent var pct = IIf(total == 0, 0, Round((michigan / total) * 100, 1)) // Create dictionary to hold percent calculation var newDict = {fields: [ {name: 'Percent', type: 'esriFieldTypeDouble'}], geometryType: '', features: [] } // Put percent calculation into dictionary Push(newDict['features'], {attributes: {Percent: pct}}) // Create a featureset from the dictionary return FeatureSet(Text(newDict))

You are returning a Dictionary, not a FeatureSet. You just need to wrap that Dictionary in the FeatureSet function
