Hello,

I am currently facing the "Unknown filter expression type" error when launching COUNT queries such as

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
SELECT (COUNT(?s) AS ?v)
WHERE { ?s rdf:type ?o . }

This only happens when actual data is found. When the query pattern does not match anything, the query does not throw any error.

Thanks.

I am getting this as well. Is there any update for this issue?
