hello everybody i am migrating to fieldmaps an arcade calculation that work perfectly in the map viewer and pro.
the subject of this calculation is : spatially catching the attribute of an other layer BUT based on the majoritary representation in multiple intersections case.
when calculating in fieldmaps seems not wait the end of the complete geometry before calculating.

console('TITRE : extraire atribut relation spatiale')

// VARIABLES UTILISATEURS
var t = 50; // tolérance maximale de recherche exprimée en mètres
var G = $feature // G pour géométrie source
var P = buffer($feature,t,'meters'); // P pour entité de type polygone
var L = FeatureSetByName($map, "ROUTES_POUR_PR") // L pour layer dont on veut l'attribut majoritaire
var A = 'ROUTE' // A pour attribut à retourner
// STEP1 : AJUSTEMENT DE LA DISTANCE DE TRAITEMENT
var I = Intersects(L,P) // I pour Intersection
if(isempty(I) || count(I)==0){return '+ de '+t+ 'mètres'}
var adjustedDistance = Infinity;
// On cherche le plus proche pour calculer sa distance
for (var sEnt in I){
var DynDistance = Distance(sEnt,G, "meters");
if(DynDistance < adjustedDistance){
adjustedDistance = DynDistance;
}
};
if(adjustedDistance==0){adjustedDistance+=1}
// STEP : 2 ADAPTATION DE LA GÉOMETRIE SOURCE
if(typeof(geometry(G))=='Polyline'|| typeof(geometry(G))=='Point')
{P = buffer(G,adjustedDistance,'meters')
console('P est une ligne ou un point')};
if(typeof(geometry(G))=='Polygon')
{P = G
console('P est un polygone')};
// STEP 3 : TRAITEMENT DES CAS D'INTERSECTION UNIQUES.
if(isempty(I)||count(I)==0){return '-'};
if(count(I)==1){
var candidat = first(I)[A]
if(right(candidat,2)=='PG'){return replace(candidat,'PG','')}else{return candidat}

var features = [];
var feat;
for (var eEnt in I){
var tmpG = clip(eEnt,extent(P))
var Geom = Buffer(tmpG,adjustedDistance,'meters')
var gArea = Area(Intersection(P,Geom),'meters')
var gAttr = eEnt[A]
feat = {'attributes': {'inheritedAttr': Text(gAttr),'representation': Number(gArea),}}
Push(features, feat);
