Importing large Tumblr site, running into import errors

[readtedium]

Hi there, I'm looking to move my Tumblr content to a static site for archival purposes. Unfortunately, that's harder than it sounds because I have more than 20,000 posts. I ran into an issue where the importer would stop because the pictures from one of my old posts were missing from the Tumblr servers, but having removed that old post I'm now running into another error:

/usr/local/Cellar/ruby/2.4.3_1/lib/ruby/2.4.0/open-uri.rb:363:in `open_http': 429 Limit Exceeded (OpenURI::HTTPError)
from /usr/local/Cellar/ruby/2.4.3_1/lib/ruby/2.4.0/open-uri.rb:741:in `buffer_open'

from -e:2:in `<main>'

I'm going to try and restart the process in a fresh directory, as I got further before the image problem cropped up (11,000 posts) than I did before this error appeared (7,000 posts). However, If there's any suggestions as to what to do to handle this to help slow down the HTTP requests so that I can avoid this problem, I'd be greatly appreciative. Thanks.

Got it working—the loading issue might be worth looking into, but downloading all the images from Tumblr had a side effect of slowing down the API enough that I didn't run into the error.
