Spring social The OAuth2 'state' parameter is missing or doesn't match

I'm developing a spring boot application and I need to use spring social login for facebook. I tried different strategies and tutorials to achieve that, but every time after user is redirected from facebook to my application, I get the error saying 'state' parameter doesn't exist or not match. I know this parameter is something like CSRF protection and I can see that spring is sending it when user is redirecting to facebook. But I almost get lost inside facebook response. I can see the parameter exists in the set-cookie header from facebook, but not as a parameter.

I can see more people have faced this issue before, but none of the answers worked for me and they were quite old questions. There is also an open issue on github about this. Is it a bug? or cant it be fixed through some configuration?

I'm using spring security and spring session redis in this project too. While I have tried many different configuration, here is the last one I have been working on:

SOCIAL CONFIG

@Configuration
@EnableSocial
public class SocialConfig
        implements SocialConfigurer
{


    private final Environment environment;
    private final MongoOperations mongoOperations;
    private final FacebookConnectionSignup facebookConnectionSignup;

    @Autowired
    public SocialConfig(Environment environment, MongoOperations mongoOperations, FacebookConnectionSignup facebookConnectionSignup) {
        this.environment = environment;
        this.mongoOperations = mongoOperations;
        this.facebookConnectionSignup = facebookConnectionSignup;
    }

    @Bean
    public TextEncryptor textEncryptor(){
        return noOpText();
    }


    @Override
    public void addConnectionFactories(ConnectionFactoryConfigurer connectionFactoryConfigurer, Environment environment) {
        connectionFactoryConfigurer.addConnectionFactory(new FacebookConnectionFactory(
                environment.getProperty("spring.social.facebook.appId"),
                environment.getProperty("spring.social.facebook.appSecret")));
    }

    @Override
    public UserIdSource getUserIdSource() {
        return new AuthenticationNameUserIdSource();
    }

    @Override
    public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
        MongoUsersConnectionRepository mongoUsersConnectionRepository = new MongoUsersConnectionRepository(
                mongoOperations,
                connectionFactoryLocator,
                new MongoConnectionTransformers(
                    connectionFactoryLocator,
                    textEncryptor()
                )
        );
        mongoUsersConnectionRepository.setConnectionSignUp(facebookConnectionSignup);
        return mongoUsersConnectionRepository;
    }

    @Bean
    public SocialUserDetailsService socialUserDetailsService(UserDetailsService customUserDetailsService){
        return new SimpleSocialUserDetailsService(customUserDetailsService);
    }

}

After around three days today I finally found the solution.

First of all, The problem I was facing was because of this exception:

2018-09-01 10:05:50.679  INFO 7169 --- [io-8080-exec-10] o.apache.coyote.http11.Http11Processor   : Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

with a little search I found out facebook has began forcing HTTPS in callback urls.

After that, I had to fix call back url. The callback url that is set in application must match valid ones in facebook setting.

So I made this change:

@Bean
    public ProviderSignInController providerSignInController(UsersConnectionRepository usersConnectionRepository, ConnectionFactoryLocator connectionFactoryLocator, FacebookSignInAdapter facebookSignInAdapter) throws Exception {
        ((MongoUsersConnectionRepository) usersConnectionRepository)
                .setConnectionSignUp(facebookConnectionSignup);

        ProviderSignInController providerSignInController = new ProviderSignInController(
                connectionFactoryLocator, usersConnectionRepository, facebookSignInAdapter);
        List<ProviderSignInInterceptor<?>> list = new ArrayList<>();
        list.add(new FacebookConnectionInterceptor());
        providerSignInController.setSessionStrategy(new HttpSessionSessionStrategy());
        providerSignInController.setSignInInterceptors(list);

    // **IMPORTANT PART** >>
    providerSignInController.setApplicationUrl("https://test.dropinmessenger.com");
        providerSignInController.afterPropertiesSet();
        return providerSignInController;
    }

after fixing the url (I could not use https on localhost, not sure even if this works on localhost), I had to provide valid callback_uri in facebook too:

The next error I faced was because I was not providing secret_proof or something close to that. The quickest fix was to turn it off from App Setting > Advanced > Require App Secret which does not seem to be safest solution.

ATTENTION Also make sure you are using latest spring-social-facebook dependency. these didn't work in version 1.1.1RELEASE, I used 2.0.3RELEASE.
