That way we can debug and offer suggestions. There may be an Arcade bug, rendering issue, or there could be an issue with the expression.</P> Tue, 19 Apr 2022 20:09:02 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/esri-renderers-uniquevaluerenderer-getsymbol/m-p/1165860#M77054 KristianEkenes 2022-04-19T20:09:02Z
