Slash in Symfony route?

Question

symfony

Good evening!
There is a route

@Route("/{slug}/", name="my_page", requirements={"slug"=".+"})

but for some reason, when navigating to mysite.com/mypage/, the $slug variable contains "mypage/", i.e. slug along with a slash.
Why does symfony add a slash to a variable and how to get rid of it?
