Fix NullPointerException

✅ Solution

NullPointerException errors in Keycloak often arise from uninitialized or null objects, especially related to the Keycloak environment or configuration. Ensure that Keycloak components and dependencies, such as `Profile` instances or DPoP related utilities, are properly initialized before being accessed. Investigate the execution order and dependency injection to guarantee that required objects are available when and where they are needed, potentially using lazy initialization or explicit initialization routines.
