Tic-tac-toe application - doesn't allow the users creation.

[fabianbch]

What are the steps to reproduce this bug?

1. All instructions for the implementation and deployment of the application were followed.
2. When entering http://localhost:10005/login and clicking on the /create option, the registered users are not created.
3. When entering /login with any user - created or not - the HTTP header remains blank with no information.

What happens?

Invalid CORS error messages are returned on user creation, the application Tic-tac-toe does not work correctly.

What were you expecting to happen?

The application does not work, when entering /statistics the page returns the invalid token message.

Any logs, error output, etc?

Any other comments?

Thanks for your help, also the packages: npm, jackson, are in obsolete or outdated versions. When I run make install I get warning messages for deprecated software versions.
