Drupal 9.2 Login not working after logout

Question

My site upgraded from Drupal 8.x to Drupal 9.2.4 (PHP 7.4). Once logout then login was not working. No error or warning, just page refresh happened. I checked the cookie compared with my old version, one of the cookies was not set after first login and logout.

The below image session is not set for second-time login.

Missing session image

I am not sure this is the problem, maybe.

Answer 1

I had the same issue. I am using my own redirect in hook_user_login(). After update from Drupal 9.1 to Drupal 9.2 my redirect stoped working (no login and no redirect). I found information on Drupal forum that 'redirect after login is breaking a basic contract of Drupal hooks, in that it is halting execution.' On the same forum I found suggestion to save session before sending a response, so I tried this on my code:

$response = new RedirectResponse($url->toString());
$request = \Drupal::request();

// Save the session so things like messages get saved.
$request->getSession()->save();

$response->prepare($request);
$response->send();

升级到 9.2 后我遇到了同样的问题......会话已打开，但无法登录。
