Problem in production when removing wrap-reload

Sat, 25 Apr 2020 16:47:42 +0000

I'm setting up a service that returns a JSON, thanks to Ring, Compojure and Jetty. The problem I have is when I want to use Nginx as a reverse proxy. If I use the following handlers it doesn't work.

(def wrapped-handler
  ;; Handler middlewares
  (-> all-routes
      (wrap-defaults (assoc-in site-defaults [:security :anti-forgery] false))
      wrap-params
      wrap-session
      ))

The message I get back is

java.lang.NullPointerException
        at ring.adapter.jetty$proxy_handler$fn__6990.invoke(jetty.clj:26)
        at ring.adapter.jetty.proxy$org.eclipse.jetty.server.handler.AbstractHandler$ff19274a.handle(Unknown Source)

But if I add wrap-reload everything goes right.

(def wrapped-handler
  ;; Handler middlewares
  (-> all-routes
      (wrap-defaults (assoc-in site-defaults [:security :anti-forgery] false))
      wrap-params
      wrap-session
      (#(if (config :debug) (wrap-reload %)))
      ))

My setup with Nginx is as follows.

server {        

        server_name domain.com;

        location / {
            proxy_pass http://localhost:9000/;
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_redirect  off;
        }
}

Is it safe to leave wrap-reload in production?
What have I left behind?

Thank you all in advance.
