getSession returns null when retrieving from requestStack in Symfony 5.3

[samuelvi]

Hi, The scenario is as follows:

• An abstract class which sets via @required the requestStack.
• A method were an auto authentication occurs
• Prior to SF 5.3 the authentication method used the session object from the SessionInterface. In SF 5.3 the session must be taken from requestStack

At this point $this->requestStack->getSession() always returns null. The following error is gotten when trying to retrieve the session from the requestStack instance:

There is currently no session available. (Symfony\Component\HttpFoundation\Exception\SessionNotFoundException)

Thanks!

P.S: Also tried to inject the requestStack via constructor but the same error happens.

I just realized that retrieving the session service directly from the container works.

So previous to SF 5.3:

public function __construct(SessionInterface $session) 
{
  $this-session = $session;
}

public function getWebSession() : SessionInterface 
{
  return $this->session;
}

And since SF 5.3:

public function __construct(KernelInterface $kernel) 
{
  $this->kernel = $kernel;
}

public function getWebSession() : SessionInterface 
{
  return $this->kernel->getContainer()->get('session');
}

Sorry about the confusion, thanks!
