Current Behavior

openid-connect plugin gives error when targetUrl and redirectUrl are same. Error we get is "request to the redirect_uri path but there's no session state found".I can see session cookie. Still we see the error.

Expected Behavior

openid-connect works when targetUrl and redirectUrl are same.
