    # The S3 bucket to which to deploy CloudFormation templates when
    # `always_upload` is set to true or the template is too big for a string

      upload_message = <<~MSG
        The %<identifier>s stack's body is too large to be use the template_body
        option, and therefore must use the template_url option instead. You can
        configure Humidifier to do this automatically by setting up the s3
        config on the top-level Humidifier object like so:

            Humidifier.configure do |config|
              config.s3_bucket = 'my.s3.bucket'
              config.s3_prefix = 'my-prefix/' # optional
            end
      MSG

      raise upload_message.gsub('%<identifier>s', identifier)
    end
    # rubocop:enable Metrics/MethodLength
  end
end
