When a request fails, for example due to a BadResponse, it would be helpful to dump the results, somehow. This is some debugging code that 'works' but not very well.

        res = ::Net::HTTP.new(uri.host, uri.port).start do |http| 
          yield(http, request) if block_given?
          
          begin
            http.request(request)
          rescue(Net::HTTPBadResponse)
            socket = http.instance_variable_get(:@socket)
            puts socket.read_all
            raise
          end
        end

I got an error by submitting the attached request. The output is:
