SAML SSO with Facebook Federated Authentication fails in WSO2 IS 5.0.0

I am following this blog post http://prasadtissera.blogspot.com/2014/04/login-with-facebook-for-wso2-identity.html to do SAML SSO with Facebook Federated Authentication. Everything works fine till Facebook redirects the request back to webapp back after authentication. In that point console gives following exception,

[2014-06-02 08:06:36,822] ERROR {org.wso2.carbon.identity.sso.saml.builders.DefaultResponseBuilder} -  Error when reading claim values for generating SAML Response

Facebook authenticator in WSO2Identity Server 5.0.0 was designed to work with Graph API 1.0, but at the moment Facebook support for v2.0 that's why this problem may have occurred. So you can write a new Facebook authenticator and plug in to Identity server. please have a look to org.wso2.carbon.identity.application.authenticator.facebook to get implementation details.
