Capistrano deployment failing on assets:precompile - ruby-on-rails

I have been using capistrano 3 for my rails app for sometime. Today it started failing at assets precompilation step with the following on logs that aren't very helpful:
On the server I have
node 10.12.0
yarn 1.10.1
rails 5.1.6
ruby 2.5.1
rbenv 1.1.1
Caused by:

Edit: My yarn.lock file looks like so:
# THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.
# yarn lockfile v1
Actually, I don't use yarn for anything--was putting up with it because Rails decided to use it by default. I'll be happy we can remove it forever and have the error above be gone with it.

Looks like you don't have yarn installed in your deployment server. Did you already installed it? If not, try this command before a new deploy:
npm install yarn -g

Add node_modules to the rails asset paths causes an asset compilation error

If I add just the following lines to my config/initializers/assets.rb on Rails 5.1 I get an asset compilation error:
assets = Rails.application.config.assets
assets.version = '1.0'
assets.paths << Rails.root.join('node_modules')
Of course, this file did contain more lines, but I've stripped it right back as part of trying to debug this. I've also emptied the application.coffee and application.scss files of all content.
This is the compilation error with --trace and RAILS_ENV=production

Tasks: TOP => assets:precompile
I am completely stumped as to where this error could be coming from given that I wouldn't expect anything to be compiled as a result of the empty application.coffee/scss, except images.
In fact, after running an assets:precompile without the node_modules includes I get only the following JS and CSS files:
$ find ./public/assets/ -name "*.js"
./public/assets//application-f78f0f583e152fa235ca51f99bab70d1aeb59675de57c78bcef18b5a2e8a5a5f.js
./public/assets//active_admin-f78f0f583e152fa235ca51f99bab70d1aeb59675de57c78bcef18b5a2e8a5a5f.js
These are both 'empty', only containing (function(){}).call(this);
$ find ./public/assets/ -name "*.css"
./public/assets//active_admin/print-ef81b6a45bca13d9584a56677a4cc64d9cb053c768465f43ef448caf6f220216.css
./public/assets//active_admin-c1ac2e411944e447bcbf94ec2d97a0f2825ec0153bcbda2925f69da7ea6db226.css
./public/assets//application-e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855.css
Here the application.css asset is completely empty. The active admin files have a lot of CSS in though.
With node_modules in the assets path leads to the syntax error shown above.
OK, so it turns out that sprockets will hungrily process any JS it finds in a directory named application!
I found this by changing my uglifier to handle ES6 syntax:
config.assets.js_compressor = Uglifier.new(harmony: true)
And then discovered that the assets compile had produced another JS file:
./public/assets//#schematics/angular/application/index-7cb879a643459c580f46b4127272b2918753e9941c074dcf27faea589ca610de.js
./public/assets//application-f78f0f583e152fa235ca51f99bab70d1aeb59675de57c78bcef18b5a2e8a5a5f.js
The file is coming from here:
$ find ./node_modules/ | grep -E "application/.*.js$"
./node_modules//#schematics/angular/application/index.js
./node_modules//#schematics/angular/application/files/karma.conf.js
./node_modules//#schematics/angular/application/files/protractor.conf.js

Styling on subpages does not work https://infinite-meadow-50968.herokuapp.com/meetups/ See the menu and the section with meetups (in the main page its working)
Can you try to precompile in local? After push it into Heroku. It may be working.
All your js files have wrong syntax for comments. You use # instead of //.
E.g. #= require froala_editor.min.js should be //= require froala_editor.min.js.
You use # for comments in coffee files, and // for js files. Please replace it in all your js files.

What's wrong with favicon.ico, sprockets and rails 5?

I'm getting the following error on my rails app when I try to precompile the assets. With a trace it says the following:
$ RAILS_ENV=production rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
