Requests hang when communicating with Incus Socket

[mamoss-oss]

Hi,
I am trying to use the unix http socket to communicate with Incus. But it seems like any communication I try either hangs, or takes very long time in its first execution and then becomes instant for every consecutive function execution. Not sure from which angle I should try to troubleshoot the issue. Also I am very new to the clojure world, but will try my best to provide details.

Thank you.

Minimal example

(ns incus-clojure.src
  (:require [unixsocket-http.core :as uhttp]))

(def client (uhttp/client "unix:///var/lib/incus/unix.socket"))
(uhttp/get client "/")

As soon as I send the get function to evaluation in the editor repl, it blocks.

Sanity check: Incus socket works when targeted with curl. No delay seen at all.

curl --unix-socket /var/lib/incus/unix.socket http://localhost/
{"type":"sync","status":"Success","status_code":200,"operation":"","error_code":0,"error":"","metadata":["/1.0"]}

I also used the example commands in the repository readme with the docker socket and did not see any issues.

Repl output with delay in the first function execution. Measured with the time function. I have no idea why it sometimes works with delay and sometimes it does not work at all.
