Cas with OAUTH logout not working

[Gopal Krishna]

Hi , i have configured CAS with Azure OpenID in my application. When user tries to logout i am invalidating TGT using CAS API "/v1/tickets" API, but when i retry to login to application the request is taken back to CAS instead of azure login screen and it throws following error as TGT is destroyed. I have tried SLO with property "cas.logout.removeDescendantTickets=true" and its deleting accesstoken and refresh token but still it does not work.

java.lang.RuntimeException: null
