[keycloak-user] Keycloak JS adapter iframe origin

[Pedro Pedro]

 We have angular app and we use nginx in a docker image to deploy it.  
  I'm trying to pass the keycloak url to the js adapter by using a constant like this:  new Keycloak(url: '/idp');  
  and in nginx's config I try to proxy that constant to the passed args to the docker image:  location /idp {  
 
 

proxy_pass ${IDP_PROTOCOL}://${IDP_ADDR}/${IDP_CONTEXT_PATH};  }  
  When the logic in checkLoginIframe tries to send cross-origin request it fails because the adapter uses our app's origin.  
  Is there any way to be able to proxy that via nginx?  
  If I disable checkLoginIframe can the session be tracked when expired and etc?
