Connecting to fusionAuth as an OAuth2 in spring boot cloud gateway(webflux)

mehdi.motrada

Hello FusionAuth,
Recently I am working on spring boot gateway(webflux) and I added fusionAuth as a oauth2 with other oauth2 provider, I added my redirection urls in fusionAuth and the redirection for log-out is working perfect but redirection after login is not working and always fusionAuth app shows me the message "404 Page Missing"!
Here is my application.yml:

spring.security.oauth2.client.registration.fusionauth-client.client-name=fusionauth
spring.security.oauth2.client.registration.fusionauth-client.scope=email,openid,profile
spring.security.oauth2.client.registration.fusionauth-client.client-secret=mSqcm75d2qH93EIGHYfVOxRlII5_KbMFyKBaTrGkTnA
spring.security.oauth2.client.registration.fusionauth-client.client-id=77d6819f-e5d1-4628-a55c-e8b089ca8e69
spring.security.oauth2.client.registration.fusionauth-client.redirect-uri=http://car-uk.localhost/auth.php5
spring.security.oauth2.client.registration.fusionauth-client.provider=fusionauth
spring.security.oauth2.client.registration.fusionauth-client.client-authentication-method=basic
spring.security.oauth2.client.registration.fusionauth-client.authorization-grant-type=authorization_code

spring.security.oauth2.client.provider.fusionauth.authorization-uri=http://localhost:9011/oauth2/authorize
spring.security.oauth2.client.provider.fusionauth.token-uri=http://localhost:9011/oauth2/token
spring.security.oauth2.client.provider.fusionauth.user-info-uri=http://localhost:9011/oauth2/userinfo?schema=openid
spring.security.oauth2.client.provider.fusionauth.user-name-attribute=name
spring.security.oauth2.client.provider.fusionauth.user-info-authentication-method=header
spring.security.oauth2.client.provider.fusionauth.jwk-set-uri=http://localhost:9011/.well-known/jwks.json

and my security configuration Bean class is:

    @Bean
    fun securityWebFilterChain(http: ServerHttpSecurity,repo: ReactiveClientRegistrationRepository): SecurityWebFilterChain {
        val logoutSuccessHandler = RedirectServerLogoutSuccessHandler()
        logoutSuccessHandler.setLogoutSuccessUrl(URI.create("/"))
        val defaultServerOAuth2AuthorizationRequestResolver = DefaultServerOAuth2AuthorizationRequestResolver(repo)
        defaultServerOAuth2AuthorizationRequestResolver.setAuthorizationRequestCustomizer(OAuth2AuthorizationRequestCustomizers.withPkce())
        return http
            .authorizeExchange {
                it
                    .anyExchange().authenticated()
            }
            .oauth2Login { login-> login.authorizationRequestResolver(defaultServerOAuth2AuthorizationRequestResolver) }
            .logout().logoutSuccessHandler(logoutSuccessHandler).disable()
            .cors().and()
            .csrf().disable()
            .build()
    }

Would you please tell me, where my mistake is?
