Identity Server 4 and auto redirect on sign out

Question

Playing around with a demo project from PluralSight, I am trying to have the IDP redirect back to the server app on sign out.

The PostLogOutRedirectUris is defined in the config for the Client at the IDP level, but it doesn't seem to have any effect.

public static IEnumerable<Client> Clients =>
    new Client[]
    { 
        new Client
        {
            ClientId = "bethanyspieshophr",
            ClientName = "Bethany's Pie Shop HRM",
            AllowOfflineAccess = true,
            AccessTokenLifetime = 120,
            RequireConsent = false,
            RequirePkce = true,
            AllowedGrantTypes = GrantTypes.Code,
            ClientSecrets = { 
                new Secret("108B7B4F-BEFC-4DD2-82E1-7F025F0F75D0".Sha256()) },
            RedirectUris = { "https://localhost:44301/signin-oidc" },
            PostLogoutRedirectUris = { "https://localhost:44301/signout-oidc" },
            AllowedScopes = { "openid", "profile", "email", "bethanyspieshophrapi" }
        }             
    };

If I manually at runtime set the LoggedOutViewModel it works as expected.

The issue was simply due to a typo, which sent me on a wild goose chase.

  PostLogoutRedirectUris = { "https://localhost:44301/signout-oidc" },

Should be

  PostLogoutRedirectUris = { "https://localhost:44301/signout-callback-oidc" },

And then, it worked.
