Hi, where should I post an issue with pedestal? With the sawtooth router
Santiago Cabrera 2025-06-10T16:02:29.777889Z
If I run this
(require '[io.pedestal.http :as http])
(defonce server (atom nil))
(defn stop-server []
(when @server
(http/stop @server)
(reset! server nil)
(println "Server stopped")))
(do (defn start-server []
(let [service (-> {::http/routes
#{["/contacts/:id" :get (constantly {:status 200}) :route-name :get-contact]}
::http/type :jetty
::http/port 8080
::http/join? false}
http/create-server)]
(reset! server (http/start service))
(println "Pedestal server running at ")))
(do (stop-server) (start-server)))
; This will return 500. You can try it in the browser.

This has not been my experience. Are you seeing a logged exception?
Your constantly should be treated as a handler function, so returning a response map should work.
hlship 2025-06-10T17:43:39.102629Z
The /contacts URL should not match your route, and one of the default interceptors, not-found, should convert that to a 404 (because no route matched, so no :response was every attached).

Agree that it should return 404, but is returning 500. This is happening the the sawtooth router from the alpha
hlship 2025-06-10T17:44:45.605709Z
Ok, that's much more helpful.
hlship 2025-06-10T17:45:07.500629Z
And it could be a bug in sawtooth, that is where the exception occurs.
hlship 2025-06-10T17:45:11.326909Z
Could you try with alpha-7?

Santiago Cabrera 2025-06-10T17:48:20.447849Z
Sure. Thanks for taking a look
