RSS import from blogger atom file Error: undefined method `strftime' for nil:NilClass

[tmray]

I'm trying to import a blogger blog to jekyll. Blogger no longer does an xml back up for sites. It makes you backup via Google Takeout now and only offers the sites feed.atom file. This of course does not work with the Blogger import method.

I tried to use the import RSS method with the atom file, but it gives this message when trying to do that with a Blogger site atom file

jekyll-import rss --source feed.xml --extract_tags KEY --canonical_link
