generating failed with a lowercased pdf extension (.pdf)

[phoenixwu]

cannot work with a lowercased extension pdf file(.pdf), such as: _posts/2019-06-02-ttt2/xxx.pdf Jekyll Feed: Generating feed for posts Liquid Exception: undefined method to_liquid' for #<Pathname:xxx.pdf> in sitemap.xml Error: undefined method to_liquid' for #Pathname:xxx.pdf Error: Run jekyll build --trace for more information.

but it works fine if I changed the extension into uppercase PDF(.PDF):

                _posts/2019-06-02-ttt2/xxx.PDF

Today I found some .doc files have the same issue, I must uppercase the extension to .DOC to make jekyll-postfiles to recognize it. Some .doc files works fine but some can't. I think maybe it's because of the filename pattern, Chinese characters or something?

In order to keep things going, I just try to disable the gem 'jekyll-sitemap' in Gemfile, and this weird issue is gone! 😕 I think this is not the root cause, but since I'm using jekyll in my local LAN only, so I don't really need the sitemap.xml in my case.

I just tried it and I can include pdf files fine. I've also got jekyll-sitemap so if that is the issue, then it's not uniquely for lowecase file extensions. Can you try running and posting with --trace and posting the exception stack?

Been a while, but I also encounter this problem (and same 'patch' of using uppercase for the extension resolves it). I ran the build with --trace and got:
