I think you got your examples backwards? The SLD parameter is used to pass a style that completely defines a map including listing all of the layers. To make this work your layers eea-urban-atlas etcc.. should be documented as user layers in your SLD file.
Try removing the layers parameter, encode the SLD url value, and try again? Actually checking the URL it redirects to https://raw.githubusercontent.com/dzelge/test-gha/main/ljubilana.sld ... so using that: https://stage.xcube-geodb.brockmann-consult.de/geoserver/eea-urban-atlas/wms?service=WMS&version=1.1.0&request=GetMap&bbox=4638735.0%2C2524481.25%2C4704972.5%2C2594978.75&width=721&height=768&srs=EPSG%3A3035&format=image/png&SLD=https%3A%2F%2Fraw.githubusercontent.com%2Fdzelge%2Ftest-gha%2Fmain%2Fljubilana.sld The result is: *Error while getting SLD. See the log for details. * I guess the next step is to check those logs. For a working example testing locally *https://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&SLD=http%3A%2F%2Flocalhost%3A8080%2Fgeoserver%2Fstyles%2Fnavigation.sld&bbox=-180.0,-90.0,180.0,90.0&width=768&height=384&srs=EPSG:4326&format=application/openlayers <https://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&SLD=http%3A%2F%2Flocalhost%3A8080%2Fgeoserver%2Fstyles%2Fnavigation.sld&bbox=-180.0,-90.0,180.0,90.0&width=768&height=384&srs=EPSG:4326&format=application/openlayers>* This has no layers parameter listed in the URL, instead the map pulls its layers from a document like *navigation.sld* like: <?xml version="1.0" encoding="UTF-8"?> <StyledLayerDescriptor version="1.0.0" xmlns="http://www.opengis.net/sld"; xmlns:ogc="http://www.opengis.net/ogc"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/sld http://schemas.opengis.net/sld/1.0.0/StyledLayerDescriptor.xsd";> <NamedLayer> <Name>ne:states_provinces_scale</Name> <UserStyle> <FeatureTypeStyle> <Rule> <Title>Administration Boundary</Title> <PolygonSymbolizer> <Fill> <CssParameter name="fill"> <ogc:Literal>#f0f0C0</ogc:Literal> </CssParameter> </Fill> <Stroke> <CssParameter name="stroke"> <ogc:Literal>#cccccc</ogc:Literal> </CssParameter> </Stroke> </PolygonSymbolizer> </Rule> </FeatureTypeStyle> </UserStyle> </NamedLayer> <NamedLayer> <Name>ne:roads</Name> <UserStyle> <FeatureTypeStyle> <Rule> <Title>Roads</Title> <LineSymbolizer> <Stroke> <CssParameter name="stroke"> <ogc:Literal>#AA3333</ogc:Literal> </CssParameter> </Stroke> </LineSymbolizer> </Rule> </FeatureTypeStyle> </UserStyle> </NamedLayer> </StyledLayerDescriptor> -- Jody Garnett On Fri, 25 Jun 2021 at 04:23, Helge Dzierzon < helge.dzier...@brockmann-consult.de> wrote: > Hi There, > > > I have an issue with using the parameter SLD in GetMap when using the WMS > service via the geoserver's API.
