Expected Behavior

I’m having a little bit of trouble serving my site running on Ruby 3.2

bundle exec jekyll serve --trace

It looks like this is a problem with liquid. It appears to be fixed in https://github.com/Shopify/liquid/issues/1625 and released in v5. It’s also a good idea to keep gem dependencies on this project up to date. Can we look into getting jekyll updated to this version of liquid so this works with the latest version of ruby?

Current Behavior

bundle exec jekyll serve
