I get the following error when I try to query a Virtuoso tied to R43ples:

query via curl:

curl -X "POST" "http://localhost:9998/r43ples/sparql" \
    -H "Content-Type: application/x-www-form-urlencoded" \
    --data-urlencode "query=select (count(*) as ?count) from <urn:testData> where {?s ?p ?o .}"

error log:

I am using R43ples 0.8.7.

Please try to uncomment the following part of the config file:

#sdd.graph.defaultContent = sdd.ttl

This should fix the error.

Is it the same error as before?
Are there any graphs in your virtuoso created by R43ples?
