SES send email - Githubissues

I'm curious if this is something you've tried or how it can be achieved, I keep getting error code 400 - BAD REQUEST

I'm able to use this similar code to retrieve private files from S3

Here is what i'm currently doing:

SES_REGION = "us-west-2"
SES_HOST   = "email.#{SES_REGION}.amazonaws.com"
KEY        = ENV["AWS_ACCESS_KEY"]
SECRET     = ENV["AWS_SECRET_KEY"]

private def creds
  Awscr::Signer::Credentials.new(KEY, SECRET)
end

private def ses_scope
  Awscr::Signer::Scope.new(SES_REGION, "ses")
end

url = String.build do |io|
  HTTP::Params.from_hash({
    "Action"                           => "SendEmail",
    "Source"                           => "test@test.com",
    "Destination.ToAddresses.member.1" => "test@test.com",
    "Message.Subject.Data"             => "test",
    "Message.Body.Text.Data"           => "test",
  }).to_s(io)
end

client = HTTP::Client.new(SES_HOST, 443, true)
client.before_request do |request|
  request.headers["Host"] = SES_HOST
  signer = Awscr::Signer::V4.new(request, ses_scope, creds)
  signer.sign
end

resp = client.get(url)
