:response-interceptor example in README doesn't seem to work

On master, when I tried out this snippet from https://github.com/dakrone/clj-http/tree/master#debugging:

(client/get "http://example.org" {:response-interceptor (fn [resp ctx] (println ctx))})

I got this:

#error {

No idea if this is a useful thing to point out (e.g. maybe that feature is getting dropped but it's not time to update the docs on master yet).

Reproduce the README Debugging section's response-interceptor example, then inspect clj_http.core/build_http_client around core.clj line 348 where the reported failure occurs. Determine whether the example or the implementation is outdated, and finish when the documented example works or the README accurately describes the supported behavior.
