Nested query params

deps

{:deps {
        org.clojure/clojure {:mvn/version "1.11.1"}
        clj-http/clj-http   {:mvn/version "3.12.3"}
        cheshire/cheshire   {:mvn/version "5.11.0"}}}

code

(require '[clj-http.client :as client])

(client/post "http://localhost:3000" {:debug true :as :json :query-params {:items [{:key1 "value"}]}})

The resulting query string (decoded) is items={:key1+"value"}
I am looking for items[0][key1]=value

Is this expected?

Reproduce the request using the provided deps and clj-http.client/post example, then trace how the :query-params option becomes the query string. Compare the current encoding of the nested vector and map with the requested bracketed form; done means nested parameters are encoded as expected, with coverage for this example.
