put Bucket Versioning API returning Signature Error

[pavo-tusker]

We tried to use the put_bucket_versioning API but we cannot make it work.
We are using SigAWS library in elixir for a signature generation

Here I provide my code and response:
` url = "http://localhost:9000/test-2/?versioning"

body = Poison.encode!(%{
VersioningConfiguration: %{
Status: "Enabled"
}
})

{:ok, %{} = sig_data, _} =
Sigaws.sign_req(url, service: "s3",
method: "PUT",
access_key: "minioadmin",
secret: "minioadmin" )
response = HTTPoison.put(url, body, sig_data, [])`
Our Signature:

%{ "Authorization" => "AWS4-HMAC-SHA256 Credential=minioadmin/20200803/us-east-1/s3/aws4_request, SignedHeaders=host;x-amz-date, Signature=8ebe222447092a680ec23b5a39a9a23c7534f553532c1d3795f02cae8edd94cc", "X-Amz-Algorithm" => "AWS4-HMAC-SHA256", "X-Amz-Content-Sha256" => "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855", "X-Amz-Date" => "20200803T123312Z", "X-Amz-SignedHeaders" => "host;x-amz-date" }

The response we are getting from Minio:
{:ok, %HTTPoison.Response{ body: "\nXAmzContentSHA256MismatchThe provided 'x-amz-content-sha256' header does not match what was computed.test-2/test-2/1627C21608F0480A628b08f3-7ffe-442d-bf96-20083da98366", headers: [ {"Accept-Ranges", "bytes"}, {"Content-Length", "347"}, {"Content-Security-Policy", "block-all-mixed-content"}, {"Content-Type", "application/xml"}, {"Server", "MinIO/RELEASE.2020-07-27T18-37-02Z"}, {"Vary", "Origin"}, {"X-Amz-Request-Id", "1627C21608F0480A"}, {"X-Xss-Protection", "1; mode=block"}, {"Date", "Mon, 03 Aug 2020 12:33:12 GMT"} ], request: %HTTPoison.Request{ body: "{"VersioningConfiguration":{"Status":"Enabled"}}", headers: [ {"Authorization", "AWS4-HMAC-SHA256 Credential=minioadmin/20200803/us-east-1/s3/aws4_request, SignedHeaders=host;x-amz-date, Signature=8ebe222447092a680ec23b5a39a9a23c7534f553532c1d3795f02cae8edd94cc"}, {"X-Amz-Algorithm", "AWS4-HMAC-SHA256"}, {"X-Amz-Content-Sha256", "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855"}, {"X-Amz-Date", "20200803T123312Z"}, {"X-Amz-SignedHeaders", "host;x-amz-date"} ], method: :put, options: [], params: %{}, url: "http://localhost:9000/test-2/?versioning" }, request_url: "http://localhost:9000/test-2/?versioning", status_code: 400 }}

Looks like the sigAws library generating the wrong signature.
