1. Add a new WMS service in the settings. In the first field, enter https://geoservices.wallonie.be/arcgis/services/FAUNE_FLORE/EP/MapServer/WMSServer?request=GetCapabilities&service=WMS 
2. Click Get Layers. The URL is generated : https://geoservices.wallonie.be/arcgis/services/FAUNE_FLORE/EP/MapServer/WmsServer?FORMAT=image/png&TRANSPARENT=TRUE&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetMap&LAYERS=&STYLES=&CRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}
3. Click OK And add the new Imagery to OSM's layers

The query doesn't work. Error message : 

<ServiceExceptionReport xmlns=""http://www.opengis.net/ogc"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" version=""1.3.0"" xsi:schemaLocation=""http://www.opengis.net/ogc http://schemas.opengis.net/wms/1.3.0/exceptions_1_3_0.xsd"">
<ServiceException code=""LayerNotDefined"">**Parameter 'layers' can not be empty.**</ServiceException>
</ServiceExceptionReport>




==== What is the expected result?

The URL should be correctly built and the layer should be displayed

==== What happens instead?

The URL is not correctly built. The Layer setting is empty.
