Steps to reproduce

Disable Basic authentication in AAP settings. Try to use one of ansible.controller modules specifying username and password, for example:

    - name: Get all credential types from AAP
      ansible.controller.export:
        controller_username: "{{ aap_config_user }}"
        controller_password: "{{ aap_config_pass }}"
        controller_host: "{{ aap_config_host }}"
        credential_types: 'all'
        validate_certs: false

Expected results

Meaningful error message saying "failed to authenticate" or "incorrect credentials" or "unable to use specified authentication method".

Actual results

Exception that doesn't help to understand what failed.

msg: This endpoint raised an error: /api/v2/credentials
exception:

good catch, I agree there should be an authentication error message in this case
