Keycloak Angular Adapter - 204 Response from login-status-iframe.html - Is This Normal?

I'm integrating Keycloak (26.1) with an Angular (19) application and observing an expected behavior that I'd like to validate.

Current Behavior: The Keycloak JS adapter makes a GET request to:

http://localhost:8080/realms/my_realm/protocol/openid-connect/login-status-iframe.html/init?client_id=my-client&origin=http%3A%2F%2Flocalhost%3A4200


which returns status 204. No errors appear in Keycloak logs.

Environment Details:

Keycloak Client:

Web Origins: http://localhost:4200
Valid redirect URIs: http://localhost:4200/*


My keycloak:

},
