Cody,

Drop the "/query?outFields=*&where=1%3D1" from your url and you will be good to go.

I tried that but it did not work. I believe it could be because I do not have access to it. I thought I set up the server connection correct but I believe I did not at this point.

Hi Cody,

I was able to make it work. Just need to drop the filter as Robert mentioned above and add the Feature layer to the map:

I still cannot get it to load, I am not sure why. If you were able to load then the rest of the code should be fine.

Here's my code:

var publicschoolsLayer = new FeatureLayer({

url: "https://services1.arcgis.com/MiBZ4u97DWldovjI/arcgis/rest/services/schools_services/FeatureServer/0/"

});

map.add(publicschoolsLayer);
