jwt_auth_token_before_dispatch not working as expected

[avks]

I am trying to fire wp_login action with jwt_auth_token_before_dispatch filter. The code I am using is something like this:

 function mod_jwt_auth_token_before_dispatch($data, $user) {
     do_action('wp_login', $user->data->username, $user);
     return $data;
 }
 add_filter('jwt_auth_token_before_dispatch', 'mod_jwt_auth_token_before_dispatch');

Although the doc specifies $data as the only argument, I see from the source code that the filter can accept two parameters: https://github.com/Tmeister/wp-api-jwt-auth/blob/a67b833992ab82c2b8fe29210a9bad03623b5045/public/class-jwt-auth-public.php#L165

But this doesn't work as expected. Instead, I found in /var/log/apache2/error.log:

[Mon Apr 15 11:42:07.347592 2019] [php7:error] [pid 31616] [...] PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function mod_jwt_auth_token_before_dispatch(), 1 passed in /var/www/.../wp-includes/class-wp-hook.php on line 288 and exactly 2 expected in /var/www/.../hooks.php:54\nStack trace:\n#0 /var/www/.../wp-includes/class-wp-hook.php(288):

Does anyone have a clue what might be causing this?

My bad. Should call add_filter with two more arguments

 add_filter('jwt_auth_token_before_dispatch', 'mod_jwt_auth_token_before_dispatch', 10, 2);
