Trouble returning wms tile in Cesium, from geoserver, vnd.ogc.se_xml

Question

I am running Cesium in sandbox, and trying to access wms layers from geoserver I am running locally on a virtual machine but having trouble returning the wms data.

The request hits the tile image, but I think nothing is being returned, or there is some issue with processing the data on the way back when trying to be processed in Cesium.

ex: the request url: https://192.168.99.100/geoserver/geonode/wms?version=1.1.0&service=WMS&request=GetMap&styles=&format=image%2Fjpeg&layers=ne_50m_admin_0_countries&srs=EPSG%3A4326&bbox=-180%2C0%2C-90%2C90&width=256&height=256

reaches an image/tile:

• the response headers: Access-Control-Allow-Origin:* Connection:keep-alive Content-Type:application/vnd.ogc.se_xml;charset=UTF-8 Date:Mon, 10 Aug 2015 19:46:08 GMT Server:nginx Strict-Transport-Security:max-age=31536000; includeSubdomains; Transfer-Encoding:chunked X-Frame-Options:SAMEORIGIN X-XSS-Protection:1; mode=block

how do i interpret the type: vnd.ogc.se_xml ?

• the errors are: An error occurred in "WebMapServiceImageryProvider": Failed to obtain image tile X: N Y: N Level: N.

• The relevant code is as follows:

  var viewer = new Cesium.Viewer('cesiumContainer');

  var provider = new Cesium.WebMapServiceImageryProvider({ url: 'url_to_wms_server', layers : 'layer_name' }); viewer.imageryLayers.addImageryProvider(provider);

any idea what's going wrong or what to change?

also, when i change the version to 1.3.0, the response type is text/xml but the url does not hit an image when i check.

If you read the WMS Spec you will see how to set the format of the error messages that the server sends you.

In this case it is clearly saying that the number 256: is invalid. Somewhere you are sending a request with that number in it, check the URL. For more information turn up the logging verbosity in GeoServer and it will send you back more details, or you could look in the log file to see what is going wrong there.
