CSV Sample erroring in map add layer ...unable to test ...

Hola Land of Red,

When I download https://developers.arcgis.com/javascript/jssamples/layers_csv.html, or visit the sandbox, run it and download, and then open the file in IE10, Firefox or Chrome, I am appear to be erroring in the call to add the csvlayer to the map. However, the code does appear to work in the live samples area and sandbox. I have checked that the url to the csv file is not being blocked.

I am trying to test whether I will be able to load a local csv file. Once I get past the error, is there any reason I would not be able to load a file on the local file system?

Thanks

also, you cannot just run the file in ie/chrome, etc.. It MUST be run/hosted on a webserver.

It's definitely a proxy issue.

You need to change the path for proxyUrl so that your application can find your proxy.

For example, when I downloaded the CSV sample from the sandbox, I too encountered an error when first trying to run the application. I was able to fix this issue by entering the correct path to my proxy.

   urlUtils.addProxyRule({
          proxyUrl: "../../proxy/DotNet/proxy.ashx",
          urlPrefix: "earthquake.usgs.gov"
        });

The index.html from the samples download, and the layers_csv.html from the sandbox download BOTH have the urlUtils.addProxyRule code.

When I try to debug into the map.addLayer(csv); line I get a 'The resource from this URL is not text: http://js.arcgis.com/3.9/' error...

Viewing the script in firebug gives me:

Thanks for the speedy reply!!!!

Do you have a proxy set up? In the code there is this line:

urlUtils.addProxyRule({
    proxyUrl: "/proxy",
    urlPrefix: "earthquake.usgs.gov"
});
