Topic on Talk:Content translation

I put the name of the existing in Ukrainian article to translate into English, but it shows that the article doesn't exist. What reasons can be? And how to start translating when the tool doesn't recognize the article?

What article was it?

I get

The "Vi skal ikkje sova bort sumarnatta" page could not be found in norsk (bokmål) Wikipediaon
