Unzipping files with Elixir throws :data_error

Question

I'm downloading a file from Google Cloud Storage (https://cloud.google.com/storage/docs/json_api/v1/objects/get#parameters)

The binary contents of the file are returned on the response body. Using :zlib.uncompress throws me

** (ErlangError) erlang error: :data_error

I've checked the contents of the file by saving it on disk and extracting manually.

Is there another way to unzip a file in elixir/erlang without using unix commands?

Edit:

Inspecting the binaries gave me an ok

r.body |> inspect(binaries: :as_binaries) |> IO.puts
<<31, 139, 8, 0, 0, 0, 0, 0, 0, 0, 212, 253, 91, 115, 27, 73, 178, 53, 10, 190, 207, 175, 104, 219, 207, 95, 193, 50, 174, 153, 57, 111, 188, 64, 36, 27, 44, 146, 6, 146, 170, 22, 95, 218, 212, 85, 234, 106, 157, 93, ...>>
:ok

You can try using zip from erlang. The function you are looking for is unzip

:zip.unzip(zipped_file)
