Good morning

I am using the following API search, which used to return title, content and link of a Wikipedia entry:

https://it.wikipedia.org/w/api.php?action=opensearch&search=alessandro%20leogrande&format=json&utf8=1

Just recently I noticed that it is always returning an empty content part ([""]):

["alessandro leogrande",["Alessandro Leogrande"],[""],["https://it.wikipedia.org/wiki/Alessandro_Leogrande"]]

Can you please give me any insight?
Thanks,
Alessandro
