The request matcher for .well-known/openid-configuration is set here:

If I change the pre method to the following, it still does not work:

    @Bean
    @Order(1)
    fun pre(http: HttpSecurity, authManager: AuthenticationManager, authProvider: AuthenticationProvider): SecurityFilterChain {
        return http.build()
    }

But if I completely remove the pre method or even just remove @Bean and @Order(1) it does work. Why does having a security filter before the oidc filter cause issues?
