NetworkError 400 - but it used to work...

AllisonAnderson — Mon, 19 Nov 2012 21:13:33 GMT

My web app was happily working until the last week or so and now I'm getting a NetworkError 400: Bad Request. I'm not sure how to troubleshoot this. Has anyone run into this?

url is http://wagda.lib.washington.edu/Aerials/AerialsViewer.html

For the most part everything works, but if I click on the Townships button, the layer won't display and Firebug gives me the 400 error. The layer is available via REST in ArcMap.

Stumped on this one.

referenceLayerUrl defined on line 104 in index.html points to a layer in the map service, but should be pointing to the root of the map service.

Change this:

var referenceLayerUrl = "http://wagda.lib.washington.edu/rest/services/Townships/MapServer/0";

To this:

var referenceLayerUrl = "http://wagda.lib.washington.edu/rest/services/Townships/MapServer";

Gah. Overlooked that as I was reorganizing services. 😮

Thanks Derek.
