Symbol could not display when turn on base map

LouPhan — Sat, 11 Dec 2021 18:18:54 GMT

I create a layer and upload to my arcgisserver, it displays well. I can see and click the symbol when i make a query.
However, when i add the base map, the symbols of query's results could not display or click.

       
map = new esri.Map("mapDiv", {

          basemap: "hybrid",// have a base map. Remove this code to delete the base map.

          center: [-34.541, 32.843],
          zoom: 3
        });

When i try to use a layer from:
http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/2
Everything works fine.

I really don't know how to fix it. Here is information of my layer.

Simple Fill Symbol:
Style: esriSFSSolid, Color: [Undefined]
Outline: 
Simple Line Symbol:
Style: esriSLSSolid, Color: [255, 255, 255, 255], Width: 1

Here is information of the sample:

When using your map service, does the query return any features back? What's the value of featureSet for showResults? What feature type is your map layer?
