ExAws.request attempting to parse XML with Jason when S3.put_bucket bucket exists

[Kip Cole]

• Do not use the issues tracker for help or support (try Elixir Forum, Slack, IRC, etc.)
• Questions about how to contribute are fine.

Environment

• Elixir 1.13
• OTP 25
• Hackney 1.18.1
• Ex_aws 2.3.2
• Ex_aws_s2 2.3.2
• Minio as the S3 server

Current behavior

The response is in XML but there is an attempt to parse it with Jason.

# Create the bucket the first time is fine
iex(11)> ExAws.S3.put_bucket("test", "local") |> ExAws.request  
{:ok,
 %{
   body: "",
   headers: [
     {"Accept-Ranges", "bytes"},
     {"Content-Length", "0"},
     {"Content-Security-Policy", "block-all-mixed-content"},
     {"Location", "/test"},

 }}

Expected behavior

The error is parsed correctly as XML
