Get Length of feature from FeaturteServer layer

[Vakhtang_Zubiashvili]

Hi guyz,

I am trying to set feature length as label on my map. From MapServer i can get it using $feature.Shape_length, but from FeatureServer it does not work, i tried to use Length($feature, 'meters') but it returns wrong data, any idea how to do?

Kind regards.

What about LengthGeodetic? https://developers.arcgis.com/arcade/function-reference/geometry_functions/#lengthgeodetic
