amazon mws - Problem with LWA Token Exchange using Selling-Partner Java SDK

Question

My code

AWSAuthenticationCredentials awsAuthenticationCredentials = AWSAuthenticationCredentials.builder()
                .accessKeyId("XXXXXXXXXXXXXXX").secretKey("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
                .region("eu-west-1").build();
        
        AWSAuthenticationCredentialsProvider awsAuthenticationCredentialsProvider = AWSAuthenticationCredentialsProvider
                .builder().roleArn("XXXXXXXXXXXXX").roleSessionName("123123123")
                .build();



        LWAAuthorizationCredentials lwaAuthorizationCredentials = LWAAuthorizationCredentials.builder()
                .clientId("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
                .clientSecret("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
                .endpoint("https://api.amazon.com/auth/o2/token").build();


        SellersApi sellersApi = new SellersApi.Builder().awsAuthenticationCredentials(awsAuthenticationCredentials)
                .lwaAuthorizationCredentials(lwaAuthorizationCredentials)
                .awsAuthenticationCredentialsProvider(awsAuthenticationCredentialsProvider)
                .endpoint("https://sellingpartnerapi-eu.amazon.com").build();

        GetMarketplaceParticipationsResponse res = sellersApi.getMarketplaceParticipations();
        List<MarketplaceParticipation> data = new ArrayList<MarketplaceParticipation>();
        data = res.getPayload();
        for (MarketplaceParticipation obj : data) {
            System.out.println(obj);
        }
