wms service I know its url and a layer name called:
I need to apply a cql_filter on a GetMap request on that layer, filtering by national cadastral reference. Tried
cql_filter=nationalCadastralReference=xxxxxxxx but it says that there is no property with
Rendering process failed PropertyDescriptor is null - did you request a property that does not exist?
How can I know the wms properties that I can filter the request with?
