I have this SPARQL query to return an item's label and the url of a Wikipedia article:

PREFIX schema: <http://schema.org/>
PREFIX wd: <http://www.wikidata.org/entity/>
SELECT ?article ?itemLabel WHERE
    { FILTER ( ?item = wd:Q10000000 )
      ?article  schema:about       ?item ;
                schema:inLanguage  "en" ;
                schema:isPartOf    <https://en.wikipedia.org/> .

      SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    }

This works as expected, but as soon as I substitute the id with Q10000000 or any higher number included, it yields no result. Not only to the entities I checked exist, but also does the query editor display a label when hovering over the id in that expression.

What is causing this behaviour and how can I adjust the query to get results for entities with ids that have an id of Q10000001 and higher?
