Identity Server 4 Silent Renew ErrorResponse: login_required

Question

I have cloned the repo from the redux-oidc-example and it works for the most part but after a few hours it gives the following error:

Action payload: ErrorResponse: login_required
at new e (oidc-client.min.js:1)
at t [as _processSigninParams] (oidc-client.min.js:1)
at t [as validateSigninResponse] (oidc-client.min.js:1)
at oidc-client.min.js:1

UserManager.js looks like this:

const userManagerConfig = {
  client_id: 'js.dev',
  client_secret: 'secret',
  redirect_uri: `${window.location.protocol}//${window.location.hostname}${window.location.port ? `:${window.location.port}` : ''}/callback`,
  response_type: 'id_token token',
  scope: 'openid email profile role offline_access',
  authority: 'http://localhost:8080',
  silent_redirect_uri: `${window.location.protocol}//${window.location.hostname}${window.location.port ? `:${window.location.port}` : ''}/silent_renew.html`,
  automaticSilentRenew: true,
  filterProtocolClaims: true,
  loadUserInfo: true
};

and my identity server config:

{
        "Enabled": true,
        "ClientId": "js.dev",
        "ClientName": "Javascript Client",
        "ClientSecrets": [ { "Value": "K7gNU3sdo+OL0wNhqoVWhr3g6s1xYv72ol/pe/Unols=" } ],
        "AllowedGrantTypes": [ "implicit", "authorization_code" ],
        "AllowedScopes": [ "openid", "email", "profile", "role", "offline_access" ],
        "AllowOfflineAccess": true,
        "AllowAccessTokensViaBrowser":true,
        "RedirectUris": [
          "http://localhost:8081/callback",
          "http://localhost:8081/silent_renew.html"
        ],
        "PostLogoutRedirectUris": [
          "http://localhost:8081"
        ],
        "AccessTokenLifetime": 900,
        "RequireConsent": false
      }

I noticed that prior to error last valid response had one cookie response(idsrv.session) with empty value with the expiry date set to the previous year:

I believe this to be the root cause of the issue, I searched it on related Github repo and tried to add the Cookie.SameSite to none but it didn't help:

services.AddAuthentication()
                .AddSaml(Configuration,externalProviders.UseSaml)
                .AddCookie(options => {
                    options.SlidingExpiration = true;
                    options.ExpireTimeSpan = TimeSpan.FromDays(30);
                    options.Cookie.SameSite = SameSiteMode.None;
                });

Any idea!

Answer 1

This is likely due to your IDP session expiring - if you call the authorize endpoint with prompt=none but it's unable to satisfy that request because no valid session exists (i.e. authentication cookie does not exist or has expired) then it will return error=login_required.

If this occurs then the correct course of action is to do an interactive (i.e. prompt=login) sign in request in the top level browser window.
