Using _anonymous user but logged in as superuser

We set up authentication in our ELK cluster.

We have an admin user with superuser role. I go to kibana, login as admin and I can login and see all the spaces.
However, when we click in a space, we get

[security_exception] action [cluster:admin/xpack/security/privilege/get] is unauthorized for user [_anonymous]

I am logged in as admin, so why is it trying to use _anonymous to access that? :face_with_raised_eyebrow:

Found the issue: I did not have elasticsearch.username nor password defined in my kibana.yml file, so it was trying to use _anonymous user.

After adding uisername and password there, everything works.
