Controller redirect not working in craft 3

Question

I am working with Craft 3 and in my controller, I am trying to do this

$this->redirect('https://foobar.test');

But it is throwing me back to the root url of my craft site. I am confused, what else do I need to do?

Answer 1

Forgot to add the return keyword :(

return $this->redirect('https://foobar.test');
