So I've been building a blog site using Jekyll and an specific theme called Chirpy, and deploying it all using Cloudflare Pages, the code is stored in a private Github repository so anytime I push code a new build gets generated by Cloudflare automatically.
It's been working fine for months but after some updates deploying a new build fails as:

Now Cloudflare allows you to specify which command you want to use in order to execute the build, that being:
bundle exec jekyll b
I've been looking for a way to update the Ruby version being used in Cloudflare and could not find any resources more than this one post. I've tried changing the Gemfile like:
spec.required_ruby_version = ">= 3.0"
, but it seems like Cloudflare does not support Ruby 3 at all; I then had the idea to use an older version of the Chirpy theme, since I already have a deployed version of the blog, I went back to Chirpy 5.2.1 but surprisingly the error persist.
Definitely adding gem "jekyll-sass-converter", "~> 2.0" to the Gemfile solved this problem, as Christian mentioned.
