Arcade Expression works in Map Viewer but not Field Maps

ChrisJRoss13

I have an arcade expression that works perfectly fine in Map Viewer but when I access the map in Field Maps it always returns "No closest weather station was found within the search distance".

Any help on why this is would be greatly appreciated.

The expression is below:

var searchDistance = 50; // Search distance in kilometers

var weatherStations = FeatureSetByPortalItem(Portal('https://www.arcgis.com'),

  '38406bada3104e258fc8b42a2a96581a',

  0,

  ['Temperature_C'],

  True

);

var proximityWeatherStations = Intersects(weatherStations, Buffer($feature, searchDistance, "kilometers"));

var minDistance = Infinity;

var closestWeatherStationTemp;

for (var f in proximityWeatherStations){

 var weatherDist = Round(Distance(f, $feature, "kilometers"),2);

 if (weatherDist < minDistance) {

     closestWeatherStationTemp = f["Temperature_C"];

     minDistance = weatherDist;

 }

}

// Check if a closest individual weather station was found before accessing its property

if (closestWeatherStationTemp != null) {

    return "Closest Weather Station Temperature is: " + closestWeatherStationTemp + " degrees C and is located approximately " + Round(minDistance,0) + " km away.";

} else {

    return "No closest weather station was found within the search distance.";

}

Are you offline when you use Field Maps? This expression would require access to the internet in order to get information from the weatherStations featureset.
