Logout fails with 400 bad request

I’m getting the following error when trying to logout a user.

Identity Provider:

Error Code: illegal_post_logout_redirect_uri

Description: The ‘post_logout_redirect_uri’ parameter must be an absolute URI that is whitelisted in the client app settings.

I’ve entered values in the general setting for Logout redirect URI (all sorts).

Please help.

When you see this error, the redirect URI it’s trying to go to will be in your address bar as a parameter. Make sure the value of that parameter is listed in your logout redirect URI settings in your Okta app.

That’s worked

Thanks a lot
