Using custom print service in app: legend doesn't show any layers

BrandonPrice1 — Wed, 18 Mar 2026 00:37:35 GMT

I created a custom print service on a stand-alone server that's used in my ArcGIS JS SDK app (in beta): Clustering - query clusters | Sample | ArcGIS Maps SDK for JavaScript. Users can zoom all the way in and select a parcel in the map. Then they can click a popup action to create some layers.

Only issue now is the legend. I wasn’t sure how I would get the legend to come through prior to creating the service. After creating it (Task: Export Web Map), I’m still not sure (fyi-legend does show using the default print utility).

Not sure if this code needs to be adjusted or it just isn't possible. Does anyone else know?

const print = new Print({ view: view, printServiceUrl: "https://rpgis.isd.lacounty.gov/arcgis/rest/services/ExportWebMap/GPServer/Export%20Web%20Map", templateOptions: { title: "EXISTING LAND USE", format: "pdf", layout: "Landscape_8.5x11_LU_Map", // Ensure you use a layout template, not MAP_ONLY attributionEnabled: false, dynamicLegendEnabled: true } });

Hi Noah,

Yes, it worked after adding the legend options in the ArcGIS Pro layout and making sure I was pointing to the right folder with the updated layout in the Export Web Map/Get Layout Templates Info geoprocessing steps.
