[Geoserver-users] Geoserver returns an exception as a response to a GetLegendGraphic request

Hi,

By what reference the version is optional? I had a look at the “Styled Layer Descriptor profile of the Web Map Service Implementation Specification” and there, in Table 9 —GetLegendGraphic operation request URL parameters the WMS version is defined to be mandatory.

GetLegendGraphics works when version is included:
http://beta.geoportal.ypen.gr/geoserver/aqd-wms/ows?service=WMS&request=GetLegendGraphic&format=image%2Fpng&width=20&height=20&layer=AM.AirQualityManagementZone&version=1.3.0

Aihe: [Geoserver-users] Geoserver returns an exception as a response to a GetLegendGraphic request

Hi,

I am using Geoserver 2.20.2.

I have configured various wms. An example is the following:

http://beta.geoportal.ypen.gr/geoserver/aqd-wms/ows?service=wms&version=1.3.0&request=GetCapabilities

In the capabilities document, I find the GetLegendGraphic request, which seems well formed based on the standard.

The version parameter is missing but it is not mandatory. I think that Geoserver is supposed to respond using the default version.

Unfortunately, when I send the request, I get the following ows exception.

ows:ExceptionTextCould not determine version</ows:ExceptionText>

Has anyone experienced the same behaviour?

Is it some configuration issue that I am missing?

Thanks in advance.

Indeed the version parameter is mandatory!

So it seems that geoserver does not form the request according to the standard.
Let’s see if there is a workaround or any configuration steps to overcome this issue…
