给定以下代码，是否可以在应用程序运行程序中调用受客户端凭据保护的API？

@Bean
public ApplicationRunner test(
    WebClient.Builder builder,
    ClientRegistrationRepository clientRegistrationRepo, 
    OAuth2AuthorizedClientRepository authorizedClient) {
        return args -> {
            try {
                var oauth2 =
                    new ServletOAuth2AuthorizedClientExchangeFilterFunction(
                        clientRegistrationRepo,
                        authorizedClient);
                oauth2.setDefaultClientRegistrationId("test");
                var response = builder
                    .apply(oauth2.oauth2Configuration())
                    .build()
                    .get()
                    .uri("test")
                    .retrieve()
                    .bodyToMono(String.class)
                    .block();
                log.info("Response - {}", response);
            } catch (Exception e) {
                log.error("Failed to call test.", e);
            }
        };
    }

该代码由于以下原因而失败：

java.lang.IllegalArgumentException: request cannot be null

全栈，
