Openidc with Keycloak error uthenticate(): request to the redirect_uri_path but there's no session state found, client

Question

I am using Openresty as a server. I have the configuration file of the nginx as per the https://eclipsesource.com/blogs/2018/01/11/authenticating-reverse-proxy-with-keycloak/.

I am getting following error "openidc.lua:1053: authenticate(): request to the redirect_uri_path but there's no session state found, client"

Can someone throw some light and try to solve the problem.

Your redirect URI must not be set to "/" but to some arbitrary path that is not supposed to return content (like /redirect_uri). It is a "vanity" URL that is handled by lua-resty-openidc
