KeyError: 'username' when authenticating with pulsar

[peterg1t]

In the documentation an example of authentication and authorization is shown in https://pulsar.readthedocs.io/en/latest/configure.html

  authentication:
    - type: oidc
      oidc_jwks_url: https://login.microsoftonline.com/xxx/discovery/v2.0/keys
      oidc_provider: azure
      oidc_username_in_token: preferred_username
      oidc_username_template: *.
  authorization:
    - type: userlist
      userlist_allowed_users:
        - xxx

In my example I setup authorization only and when app.yml is configured with this I get the following error:

This is my full config file:

Is this a real issue or am I doing something wrong here? Thank you very much in advance for your help!
