Content from a spreadsheet Error

Hi, I am following the guide Content from a Spreadsheet, copying everything like the guide says into the plainkit. After several attempts I still get the error:

Declaration of AnimalsPage::children() must be compatible with Kirby\Cms\Page::children(): Kirby\Cms\Pages

I have tried changing the file path from ‘/animals.csv’ to ‘/content/animals/animals.csv’ which didn’t help.

I am very unexperienced with this but for a project I need to be able to create content from a csv file.

Any Idea how to solve this?

Must be

public function children(): Pages
{
 // ...
}

fixed now in the docs.
