Spring Security Facing 401 error after successful SAML2 logout

@jzheaux I have implemented SMAL2 login and logout using Spring Security 6.0.1. I have followed https://github.com/spring-projects/spring-security/issues/12111#issuecomment-1297239583 to override SAML2 logout successful URL.

I am facing 401 (Unauthorized - logout/saml2/slo?SAMLResponse=nVI7b4M....) error after successful logout from the IDP.

http .logout((logout) -> logout.logoutSuccessUrl("/myLogoutSuccessUrl")) .saml2Logout(Customizer.withDefaults())

How can I redirect the custom logout url after successful SAML2 logout? Please guide me on this.
