No valid parser for XML when pushing on GitHub with external source for posts. (Feedjira::NoParserAvailable)

Acknowledge the following

• I carefully read and followed the Getting Started guide.
• I read through FAQ and searched through the past issues, none of which addressed my issue.
• The issue I am raising is a potential bug in al-folio and not just a usage question.
  [For usage questions, please post in the Discussions instead of raising an issue.]

Describe the bug
Locally, my website runs smoothly, with external source for blog posts (from Medium). When pushing the master branch of my website, I get the following error: No valid parser for XML. (Feedjira::NoParserAvailable), and the deployment step fails.

System (please complete the following information):

• OS: Windows, but I guess here the problem is on GitHub's side
• Jekyll version : locally, 4.3.1, on Github 4.3.3
• Ruby version : locally 3.1.1, on GitHub 3.0.2

Is it possible that a dependency is missing in the docker image @pourmand1376?

[george-gca]

Do you run it locally using docker?

[theosaulus]

Yes, I'm on Windows, I use Docker.

[pourmand1376]

I don't think this is related to the docker image as he says it happens only when pushing to github (not local).

For me, I add bundle add webrick before bundle exec jekyll build and specify Jekyll to a specific version in Gemfile(for me I use gem 'jekyll', '4.3.2'). This solved my problem.

Thanks a lot! I believe it's not only linked to the two things you mentioned, I also had to use gem 'mini_racer','~>0.6.2' in Gemfile. Now it works
