Getting Null pointer exception at OidcAuthorizationCodeAuthenticationProvider inspite of getting id/access tokens in Rest Template interceptor

I am trying to integrate Spring Security in my Spring Boot project using below dependency
Please not Sprint boot starter version is 3.2.0

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>

I have a SecurityConfig class with RestTemplate configurations for getting the access token. I am able to see the id_token and access_token in the log file which is given by rest interceptor, but at the end I get white label error page due to null pointer exception at line no 149 which is related to additional parameters mentioned in the Subjected class.

What I am doing wrong here? Can someone help me on this issue, been stuck on this from last 3-4 days. Does rest template needs more configurations with respect to MessageConverter or anything else I have missed.

I want to see my application loaded with Spring Security configured.
Tried the mentioned approaches in the docs of Spring Security
