Keycloak Login Screen Appears, But Authorization Fails with Errors

[Akhil-Sai-Prasad]

I've integrated Keycloak into my Angular 19 application using keycloak-js (v19.0.2). On application startup, the login screen appears as expected and I can successfully log in. However, after authentication, I'm encountering issues with an issue.

I've attached relevant screenshots for reference.
