Hi, I need help troubleshooting an error:  
After running this in the terminal:  
bundle exec jekyll serve --open-url [http://localhost:4000/](http://localhost:4000/) --trace  
I get this error:

Thank you @rdyar for your help. I asked chatGPT about it and was advised to remove the ‘jekyll-liquify’ gem and then run bundle and it built as expected. I’m not sure why I had the jekyll-liquify gem in there anyway. I guess it’s not needed to render the code?

it looks like that gem allows you to use liquid inside a frontmatter variable. As long as you are not doing that you should be fine. But since you had it in there maybe you are using it somewhere?
