These can be enqueued one at a time using rails console on era-app-prd-4 like this:

item=Item.find('1b2e4301-26ff-4f57-8133-4b67e7a60857')
item.push_entity_for_preservation

I had no luck with other items, always complaining about "the request entity is too large" error.

I have a quick code-intrusive workaround. The idea is to create aip without cleaning up, therefore,
the created packages can be uploaded using the swift command line (I tried
a file as big as 30GB a long time ago)

In the aip.rb file, comment out two lines and add two logging lines

    .....
    ensure
      #FileUtils.rm_rf(aip_filename)
      #FileUtils.rm_rf(aip_directory)
      print("HENRY: aip_filename=#{aip_filename}\n")
      print("HENRY: aip_directory=#{aip_directory}\n")
    end
