Haml version installed is '6.0.3' - this will be default with current Gemfile. Works well with haml 5.2.2.

Thanks for that, great bug report. I'll push a fix today and release a new gem.

I've just released version 0.13.0, which pins Haml to < 6.0 and also includes a few other changes.

I've tested it with Ruby 2.7, as well as Ruby 3.0 and 3.1.
