Authentication error for the Admin Dashboard in Elastic Beanstalk

Bug report

Describe the bug

I have a similar problem to the one described in issue 5415. I have followed all the steps to configure Medusa in Elastic Beanstalk, but it still presents the following problem:

My POST auth request to login into the Admin Dashboard is returning 200, but without the attribute "Set Cookie". Because of that, it become impossible to effectively login and use the admin dashboard.

I tried to customize my Ngix in the way below, but it doesn't make any effect to solve the issue:

location / {
    proxy_pass          http://127.0.0.1:8080;
        proxy_http_version  1.1;

        proxy_set_header    Connection          $connection_upgrade;
        proxy_set_header    Upgrade             $http_upgrade;
        proxy_set_header    Host                $host;
        proxy_set_header    X-Real-IP           $remote_addr;
        proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto   $scheme;
        proxy_pass_request_headers on;
        proxy_cookie_path / /;
        proxy_redirect off;
        proxy_buffering off;
}
