Okta Angular: Error: The 'post_logout_redirect_uri' parameter must be a Logout redirect UR-CodePudding

When I try to log out it displays this:

400
Bad Request
Your request resulted in an error. The 'post_logout_redirect_uri' parameter must be a Logout redirect URI in the client app settings: https://dev-81234586-admin.okta.com/admin/app/oidc_client/instance/0oa57yhuuyEUUMMqN5d7#tab-general

this is my configuration of application:

Sign-in redirect URIs 
Allow wildcard * in login URI redirect.
http://localhost:4200/callback

Sign-out redirect URIs 
http://localhost:4200/sign-out

this is my full URL:

At the end of URL I see this: &post_logout_redirect_uri=http://localhost:4200 I dont know if it has a relation with the problem

CodePudding user response：

Yes, your post_logout_url parameter in your request to /logout end-point has different URL, than configured for your application

CodePudding user response：

Your configuration indicates that the post_logout_redirect_uri should be http://localhost:4200/sign-out but you are passing http://localhost:4200 instead.
Since the URLs do not match, Okta will not redirect you, since the sign out URL needs to be whitelisted.
Change the post_logout_redirect_uri parameter in you request to match the URL you have configured.
