https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/support-for-workspacelayer-in-dynamic-map-service/m-p/1693887#M88343 <P>Hi, I found out today that LYRX Dynamic Workspace isn’t supported in the ArcGIS Maps SDK for JavaScript. I’m trying to use it in Experience Builder 1.19.<BR />As a workaround, I used&nbsp;<FONT face="courier new,courier"><SPAN>mapImageLyr.customParameters</SPAN></FONT> to pass complete LYRX Dyn Wrks definition and used minimal sublayer info (id/title/visibility) in SubLayer object so the app can control sublayer visibility and map service sublayers. It works for my use case, but it’s not a full Dynamic Workspace implementation.</P> Wed, 01 Apr 2026 13:08:31 GMT ZdeněkJankovský 2026-04-01T13:08:31Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/support-for-workspacelayer-in-dynamic-map-service/m-p/1655460#M87692 <P data-unlink="true">We want to support dynamic layers via lyrx file in dynamic MapService, but it seems it's only possible via ArcGIS REST API: see <A href="https://developers.arcgis.com/rest/services-reference/enterprise/export-map/#request-parameters" target="_self">dynamic layer setting with workspaceLayer support</A>. The same thing is not supported in Maps SDK, I got an error from Accessor that the given property value 'workspaceLayer' is invalid and needs to be one of 'DataLayerSource or MapLayerSource'. This fully corresponds with the <A href="https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-support-Sublayer.html#DynamicDataLayer" target="_self">Maps SDK documentation</A>, no words about workspaceLayer in DataLayer section (only table, query table, raster and jointable).</P><P>So the question is: is it intended that the SDK does not support this type of data layer source for dynamic Map services and if yes, when will SDK catch up with this very interesting REST functionality?</P> Mon, 06 Oct 2025 13:29:01 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/support-for-workspacelayer-in-dynamic-map-service/m-p/1655460#M87692 ImreZuber_VertiGIS 2025-10-06T13:29:01Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/support-for-workspacelayer-in-dynamic-map-service/m-p/1693887#M88343 <P>Hi, I found out today that LYRX Dynamic Workspace isn’t supported in the ArcGIS Maps SDK for JavaScript.
