What's the issue?

Previously, the Authelia example was working fine.

However, following some update, Authelia now gives the following error:

Access Request failed with error: Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method). The request was determined to be using 'token_endpoint_auth_method' method 'client_secret_post', however the OAuth 2.0 client registration does not allow this method. The registered client with id 'kitchenowl' is configured to only support 'token_endpoint_auth_method' method 'client_secret_basic'. Either the Authorization Server client registration will need to have the 'token_endpoint_auth_method' updated to 'client_secret_post' or the Relying Party will need to be configured to use 'client_secret_basic'.

Following that suggestion, I added the line token_endpoint_auth_method: client_secret_post to the client config, giving

- id: kitchenowl
    description: KitchenOwl
    secret: # Same as OIDC_CLIENT_SECRET
    public: false
    authorization_policy: two_factor # Can also be one_factor if you need less security
    pre_configured_consent_duration: 1M # One month - change this to something you desire
    audience: []
    scopes:
        - openid
        - email
        - profile
    redirect_uris:
        - https://your.domain.here/signin/redirect # Put the same value as FRONT_URL, appended with /signin/redirect
        - kitchenowl:///signin/redirect
    response_modes:
    userinfo_signing_algorithm: none
    token_endpoint_auth_method: client_secret_post # Configure custom authentication method

Was there a change in the authentication method?

Thanks for the tip, yes I've changed the auth method because someone requested it https://github.com/TomBursch/kitchenowl/discussions/406. I'll update the release notes to reflect the breaking change and docs. Thanks!
