potentially by hackney: benoitc/hackney#464

seems like we have the latest hackney 1.15.2 already but with old version of httpoison. Might be old version of httpoison using old version hackney under the hood and cause this? (I am not sure how mix.lock works. Does dependency of dependency got override?)

If httpoison could be potential cause, we might want to consider bumping the version of it.
