I have a feature class related to a table through the TRT_GUID field. The arcade expression below is entered into the field form, but the guid will not populate.
It's odd because the expression returns a field when tested, but nothing happens within field maps.
var ftrId = $feature.TRT_GUID;
if (IsEmpty(ftrId) == True || ftrId == '{00000000-0000-0000-0000-000000000000}'){
ftrId = Guid();
return ftrId
}
