hackney >= 1.24 body already consumed on HTTP redirect + pool option #503
Description
This commit fetches (and discards) the body of the request of redirect responses when custom :pool option is used, to overcome some kind of resource leak.

{:error, :req_not_found}
I guess base.ex should be adjusted to also check for these response codes (in presence of the :pool option) in order to circumvent the :req_not_found error and just return the request w/ empty body? If you agree I'll create a PR.
