WSO2 Identity Server 5.7.0 Oauth/OpenId Connect Logout has Error about session state?

this is my error:

access_denied opbs cookie not received Missing session state.

and this is my code:

 client = new HttpClient();
 var response3 = await client.GetAsync("https://localhost:9443/oidc/logout?id_token_hint=" + id_token + "&post_logout_redirect_uri=http://localhost:49545/Home/Contact");

This logout request has to be sent via the browser. If you sent the logout request as a backend request, the relevant cookies will not be passed and the logout will not be processed correctly since WSO2 IS is looking for the the cookies in order to proceed.

  • No, the idea is to send the logout request from the browser itself without making the request from backend. So the cookies will be automatically included in the request. – Sajith Apr 15 '21 at 16:10
