Hi, thanks for replied. When I tried to use that curve format, it shows error: { code: 1500, description: 'Incorrect geometry type.' }.

My format is :

geometry: {type: 'polyline',// paths: [[[ item.from_geo[1], item.from_geo[0] ], [ mid1, mid0 ], [ item.to_geo[1], item.to_geo[0] ]]],curvePaths: [[[ item.from_geo[1], item.from_geo[0] ], [ mid1, mid0 ], [ item.to_geo[1], item.to_geo[0] ]]],spatialReference: { wkid: 4326 },},
