The query below is giving me exception.

Do I need to configure stardog to running service queries?

prefix g: <http://geophy.com/>

select * where {
 SERVICE <http://admin:admin@localhost:5820/annex/geonames/sparql/query> { 
       ?loc geo:hasGeometry ?a .
    }  
 ?hq geo:hasGeometry ?b  .
 ?a geof:nearby (?b 1 <http://qudt.org/vocab/unit#Kilometer>).
}
 limit 10
