This is the code:<BR /><BR /></P><LI-CODE lang="javascript">const viewManager = MapViewManager.getInstance(); const mapView = viewManager.getJimuMapViewById(viewManager.getAllJimuMapViewIds()[0]) const [jimuMapView, setJimuMapView] = useState&lt;JimuMapView&gt;(mapView); // State for JimuMapView const [mapReady, setMapReady] = useState(false); // State to track map readiness useEffect(() =&gt; { if (jimuMapView) { reactiveUtils .whenOnce(() =&gt; jimuMapView.view.ready) .then(() =&gt; { setMapReady(true) } ) } }, [jimuMapView]) return ( &lt;div className="widget-demo jimu-widget m-2"&gt; { props.useMapWidgetIds &amp;&amp; props.useMapWidgetIds.length === 1 &amp;&amp; ( &lt;JimuMapViewComponent useMapWidgetId={props.useMapWidgetIds?.[0]} onActiveViewChange={activeViewChangeHandler} /&gt; ) } {mapReady ? 'Map ready' : 'Map not ready'} &lt;/div&gt; ); };</LI-CODE><P>&nbsp;</P><P>Thanks in advance!</P> Sat, 20 Jul 2024 14:50:11 GMT ShahranNewaz 2024-07-20T14:50:11Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/connecting-to-map-and-getting-all-the-layers/m-p/1507548#M85072 <P>Hey, so I was working on a custom widget for Experience builder and my code was running perfectly fine up until yesterday, where it stopped being able to access the layers.
