You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: handler.rb
    path of file: ./repos/aws-sdk-ruby/gems/aws-sdk-core/lib/seahorse/client/h2
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

begin
  requi
    
        def _send_initial_data(req, stream)
          begin
            data = req.body.read
            stream.data(data, end_stream: true)
          rescue => e
            raise Http2InitialRequestError.new(e)
          end
