Error in signinresponse not managed

[gogolander]

Hi,

i think there could be an error whenever the library tries to create a session and the IAM responds with an error: if the GET https://{{oidc_authorization_endpoint}}?client_id=foo&redirect_uri={{my_app}}&response_type=code&scope=openid&state={{state}} results in the following redirect {{my_app}}?error=login_required&state={{state}}&iss={{iam}} the library does nothing to handle the error.
It looks to me that, in this case, the OidcClient.processSigninResponse() should clear all user session data in the sessionStorage and start a new login request with a new state.

Am I missing something?

I'm using:

• IAM: Keycloak v25.0.2
• Oidc-client-ts: v3.4.1
• React: v18.3.1
• OAuth2.0 flow used: authorization_code
• The service provider is set with public access type
