Track Down Ruby-on-Rails "RunTimeError"

Question

I am new to this Ruby-on-Rails stuff and cannot figure out who to resolve this "RunTimeError"

When I run the following command from /var/www/discourse,

sudo -u www-data RAILS_ENV=production $ruby_path/bundle exec rake db:migrate --trace

...part way through the run, I get the following errors lines...

MiniRacer::RuntimeError: Error: Could not find module `discourse/lib/utilities` imported from `(require)`
JavaScript at missingModule (<anonymous>:247:11)
JavaScript at findModule (<anonymous>:258:7)
JavaScript at requireModule (<anonymous>:24:15)
JavaScript at <anonymous>:26:11
/var/www/discourse/vendor/bundle/ruby/3.1.0/gems/mini_racer-0.6.3/lib/mini_racer.rb:228:in `eval_unsafe'
...

Mini_racer is installed.

discourse/lib/utilities is NOT listed in the source code. Click here to view Github source code

Note: Yes, I know that the official way to run Discourse is with Docker. I am trying to figure out how Ruby-on-Rails pieces fall together and Discourse is what I am fiddling with.

Here is the rvm info output...
