foaf:isPrimaryTopicOf to find a wikipedia resource in dbpedia

Hello everybody.
Sorry if I’m putting this thread in the wrong category.

I’m trying to understand how the question of multiple languages works in wikipedia and dbpedia, as well as the insertion of data in DBPedia.

My doubt is that some wikipedia pages, some old by the way, do not appear in dbpedia. I am analyzing through http://pt.dbpedia.org/sparql and through https://dbpedia.org/sparql

An example of a Brazilian wikipedia page opened in 2018 http://pt.wikipedia.org/wiki/Pedro_Scooby

I do the sparql query below on the 2 endpoints with the query below and I don’t find any results

SELECT ?property ?value
WHERE {{
    ?entity foaf:isPrimaryTopicOf <http://pt.wikipedia.org/wiki/Pedro_Scooby> ;
            ?property ?value .
}}

I tried using the dbo:wikiPageID but that didn’t work either.

SELECT ?entity ?property ?value
WHERE {{
    ?entity dbo:wikiPageID 6744830 ;
            ?property ?value .
}}
