Problem Description:

While upgrading Keycloak from version 11 to version 26.0.0 and importing the existing realm and client configuration, I'm experiencing unexpected authentication redirect behaviors:

Authentication redirect URI is being appended with an issuer identifier
Token endpoint is being repeatedly hit
Authentication flow is not completing smoothly

Specific Observations:

Redirect URI: http://localhost:3000/individual/dashboard
Appended URI: #iss=http%3A%2F%2Flocalhost%3A9090%2Frealms%2F<realm_name>
Authentication flow is disrupted during migration

Environment:

Upgrade Path: Keycloak v11 → v26.0.0
Migration Method: Imported existing realm and client configurations
React Frontend
Authentication Library: keycloak-js
Realm: PaisaPlan
Client ID: PaisaPlanBackend

Current Configuration:

const initOptions = {
  url: `${process?.env?.REACT_APP_KEYCLOAK_URL}/`,
  realm: `${process?.env?.REACT_APP_KEYCLOAK_REALM}`,
  clientId: `${process?.env?.REACT_APP_KEYCLOAK_CLIENT_ID}`,
  onLoad: 'login-required',
  checkLoginIframe: false,
  flow: 'standard',
  redirectUri: 'http://localhost:3000/individual/dashboard'
}

Potential Migration-Related Concerns:

Configuration compatibility between v11 and v26.0.0
Changes in authentication flow or redirect handling
Imported client settings may not be fully compatible

Seeking Help:

Guidance on smooth Keycloak version migration
Resolving authentication redirect issues
Verifying client and realm configuration compatibility
Preventing unexpected URI appending and repeated token calls

Additional Context:

Realm and client configurations were directly imported from v11
Using React frontend with keycloak-js for authentication

Hi @Vinay2599
Sorry to bother you, has your problem been resolved?
I encountered a similar problem as you.
After successful login and token issuance, the redirect page looks like it is filled with a lot of iss. And the redirect endpoint is being repeatedly hit.
