my workaround

config/initializers/request_profiler.rb

if defined?(Rack::RequestProfiler)
  module Rack
    class RequestProfiler
      def format(printer)
        case printer
        when ::RubyProf::FlatPrinter
          'txt'
#        when ::RubyProf::FlatPrinterWithLineNumbers
#          'txt'
        when ::RubyProf::GraphPrinter
          'txt'
        when ::RubyProf::GraphHtmlPrinter
          'html'
        when ::RubyProf::DotPrinter
          'dot'
        when ::RubyProf::CallTreePrinter
          "out.#{Process.pid}"
        when ::RubyProf::CallStackPrinter
          'html'
        else
          'txt'
        end
      end
    end
  end
end

It looks like same workaround is still relevant
