I am using asset pipeline with uglifier. Turns out, that uglifier breaks on of js library. I am trying to trace it down, but got stuck.
So in production.rb I have config.assets.js_compressor = :uglifier but it seems is not using uglifier gem from bundle show uglifier - I put there some debug statements and they don't show.
I will dive into rails code now, but if someone knows, how rails js_compressor lookup works, would be helpful. I am using Rails 5.2
