Ruby on rails 带aws elasticsearch的Searchkick

我在searchkick和elasticsearch以及使用法拉第（faraday_）中间件-aws-signers-v4 gem方面有问题。如果我将elasticsearch.rb初始值设定项留空，它将在开发端工作。但是，如果我为AWS Elasticsearch输入配置，我会得到一个json解析错误。这是我的elasticsearch.rb文件：

require 'faraday_middleware/aws_signers_v4'

Searchkick.aws_credentials = {
  access_key_id: ENV["AWS_ACCESS_KEY_ID"],
  secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],
  region: "us-west-2"
}

我遵循了AWS github页面上的说明。我省略了ENV['ELASTICSEARCH_URL']，因为它是在我的ENV文件中定义的。我在那里试过了，结果也一样。我也试过这种方法，这是旧的方法，它应该有它，并得到同样的结果：

require 'faraday_middleware/aws_signers_v4'

Searchkick.client =
  Elasticsearch::Client.new(
    url: ENV['ELASTICSEARCH_URL'],
    transport_options: {request: {timeout: 10}}
  ) do |f|
    f.request :aws_signers_v4, {
      credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']),
      service_name: "es",
      region: "us-west-2"
    }
  end

不过，我已经能够将其缩小到这种配置

编辑：这是完整的错误输出：
