[cas-user] CAS 6.1.7 - SAML2 Attribute Query

[Sven Specker]

Hi!









java.lang.NullPointerException: null

        at java.lang.reflect.Method.invoke(Method.java:566) ~[?:?]


<snip>




The only option I found to control SAML2 AQs was activating the endpoints.



Can anyone point me in the right direction?

Thanks!

I have got a shib3 SP registered at my CAS and it tries to do an AttributeQuery. While the SP-initiated login with a browser works fine and tickets are generated, as soon as I try to do an Attribute Query using the SP itself, I run in a null pointer exception. CAS basically receives and validates the SOAP request of the SP, finds the appropriate service definition, validates the signatures successfully and then throws up without being very helpful about the reason: 2020-08-25 15:27:15,730 ERROR [org.apereo.cas.support.saml.web.idp.profile.query.Saml2AttributeQueryProfileHandlerController] - <null> at org.apereo.cas.support.saml.web.idp.profile.query.Saml2AttributeQueryProfileHandlerController.handlePostRequest(Saml2AttributeQueryProfileHandlerController.java:61) ~[cas-server-support-saml-idp-web-6.1.7.1.jar:6.1.7.1] at jdk.internal.reflect.GeneratedMethodAccessor356.invoke(Unknown Source) ~[?:?] at jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:?] 2020-08-25 15:27:15,731 DEBUG [org.apereo.cas.web.FlowExecutionExceptionResolver] - <Ignoring the received exception [java.lang.NullPointerException] due to a type mismatch with handler [org.apereo.cas.support.saml.web.idp.profile.query.Saml2AttributeQueryProfileHandlerController#handlePostRequest(HttpServletResponse, HttpServletRequest)]> 2020-08-25 15:27:15,731 DEBUG [org.apereo.cas.web.FlowExecutionExceptionResolver] - <Ignoring the received exception [java.lang.NullPointerException] due to a type mismatch with handler [org.apereo.cas.support.saml.web.idp.profile.query.Saml2AttributeQueryProfileHandlerController#handlePostRequest(HttpServletResponse, HttpServletRequest)]> 2020-08-25 15:27:15,731 ERROR [org.springframework.boot.web.servlet.support.ErrorPageFilter] - <Forwarding to error page from request [/idp/profile/SAML2/SOAP/AttributeQuery] due to exception [null]> The error messages did not enable me to track the problem down. Null pointers are nasty and maybe I overlooked an option... --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
