"State" parameter is too short with @EnableOAuth2Sso

[Oleg3n]

Auth request from Zuul app to ORY Hydra returns "The state is missing or has less than 8 characters and is therefore considered too weak" error. The generated by spring request is like "/oauth2/auth?client_id=my-client3&redirect_uri=http://127.0.0.1:8099/login&response_type=code&scope=openid%20offline&state=bl891E" where "state" param is 5 or 6 chracters length.
The app has 2 classes:

@EnableDiscoveryClient
@EnableZuulProxy
@SpringBootApplication
public class Zuul5Application {

	public static void main(String[] args) {
		SpringApplication.run(Zuul5Application.class, args);
	}
}

@EnableOAuth2Sso
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		http
			.anonymous()
				.disable()
			.httpBasic()
				.disable()
			.authorizeRequests()
				.antMatchers("/login**", "/webjars/**", "/error**", "/oauth2/**")
					.permitAll()
				.anyRequest().authenticated()
			;
	}
}

application.yml

      token-info-uri: ${app.adm-server}/oauth2/introspect

Is something wrong with configuration?

Facing the same issue. Has this been solved for you? Below is my configuration:

security:
    basic:
        enabled: false
    oauth2:
        client:
            clientId: pgm-backend
            clientSecret: QYXs34SNyBAN2aLHZL6YuBOkmTnqyWQCJw==
            accessTokenUri: https://auth.************.com/oauth2/token
            userAuthorizationUri: https://auth.************.com/oauth2/auth
            redirectUri: http://localhost:9095/authorize
            scope:
              - openid
              - offline
        resource:
            userInfoUri: https://auth.************.com/userinfo
            preferTokenInfo: false

Are you guys able to generate a token after redirect?

[ryzmd]

@akohli96 Not really. . I'm stuck with multiple redirects back and forth ending with ERR_TOO_MANY_REDIRECTS

[akohli96]

I am stuck too. After authenticating user, I cant seem to generate the token.https://stackoverflow.com/questions/54605167/unable-to-expose-endpoint-in-spring-boot-to-receive-authorization-code-from-goog?noredirect=1&lq=1

@Oleg3n I was able to solve this issue, I wrote my own AuthorizationRequestResolver which implements OAuth2AuthorizationRequestResolver. That resolver was taking care of creating state parameter. And my resolve method builds OAuth2AuthorizationRequest which uses a custom StateGenerator where I give the length as 32.

Now bean of this is added to the http.oauth2login() method in the following way.

               .oauth2Login()
                    .authorizationEndpoint()
                        .baseUri(authorizationUri)
                        .authorizationRequestResolver(customAuthorizationRequestResolver())
                        .and()
