Hi all,
I've found a 403 forbidden response with a SPARQL federated query. I simply
tested:
SELECT *
WHERE {
service <https://query.wikidata.org/sparql> {
?s ?p ?o
}
}
LIMIT 10
Using a Virtuoso endpoint like:
https://contrattipubblici.org/sparql it
works fine!
But using a local Blazegraph instance it returns:
java.util.concurrent.ExecutionException:
java.util.concurrent.ExecutionException:
org.openrdf.query.QueryEvaluationException: java.lang.RuntimeException:

cause=java.util.concurrent.ExecutionException:
java.util.concurrent.ExecutionException: java.lang.RuntimeException:

Knowing that the Wikidata SPARQL service is built upon Blazegraph, could it
be a conflicting configuration of your nginx? Or do you have any other
suggestion?
Our endpoint does not currently support queries. We are in the process
of allowing federation with a limited number of other endpoints. There
will be a page tomorrow for figuring out which ones to start with.
Cheers
