Sessions are not deleted or reassigned in laravel - what's the matter?

Question

Sessions

I set the test session in the AppServiceProvider. Session::put('bla', 'бла-бла')
I successfully display it in the template session()->get('bla')
. But then I can neither delete nor reassign it.
I'm trying to delete: Session::forget('bla')- nifiga, it is still displayed in the template.
I also tried to reassign it - it's pointless.
I created a new one-time session via Session::flash() - it turned out to be not one-time, and now it is always output and is not deleted.
How so?
How to get rid of an open session?

Answer 1

I don't see the error, try this
$request->session()->forget('bla');
