Issue in Updating Unique Value Renderer of Hosted Feature Layer

Hi Community,

I am trying to modify the unique value renderer of a hosted feature layer. I do not get any error on executing save() operation of the layer but the unique value renderer of the layer changes in simple renderer (default renderer of feature layer).

I have attached my JS code below. Kindly let me know what I must be doing wrong.

import FeatureLayer from "@arcgis/core/layers/FeatureLayer.js"; import UniqueValueRenderer from "@arcgis/core/renderers/UniqueValueRenderer.js"; const layer = new FeatureLayer({ portalItem: { id: ""//Hosted Feature Layer id. } }); const tempRenderer = layer.renderer.clone().toJSON(); const UniqueValueInfoTemp = { label: "",//label of name symbol: newSymbol, //Picture Maker symbol value: "" //same as label }; const uniqueValueGroup = tempRenderer.uniqueValueGroups[0].classes; const newClass = { label: "",//label of name symbol: newSymbol, //Picture Maker symbol value: "" //same as label }; uniqueValueGroup.push(newClass); uniqueValueInfos.push(UniqueValueInfoTemp); const renderer = UniqueValueRenderer.fromJSON(tempRenderer); layer.renderer = tempRenderer; layer.refresh(); await layer.save();

Regards,
Mani

Guessing the issue where you are creating the UniqueValueRenderer. Please take a look at this doc and make sure you are setting everything right: https://developers.arcgis.com/javascript/latest/visualization/data-driven-styles/unique-types/

Hi @UndralBatsukh ,

I have checked my JSON Object against the one mentioned in the link you provided they turn out to be same.
