I am perplexed by the following issue:

When launching a rails server in production using the following command: bundle exec rails s -e production, I get a LoadError:

=> Booting Puma
=> Rails 6.1.4.4 application starting in production 
=> Run `bin/rails server --help` for more startup options

However, when I launch rails within the development environment, everything works fine. I can't seem to find the issue. Why is this?

The full gemfile:

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '3.0.0'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails', branch: 'main'
gem 'rails', '~> 6.1.3', '>= 6.1.3.1'
# Use postgresql as the database for Active Record

# Use Puma as the app server

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder

# Use Redis adapter to run Action Cable in production

# Use Active Storage variant

# Reduces boot times through caching; required in config/boot.rb

# Use Rack CORS for handling Cross-Origin Resource Sharing (CORS), making cross-origin AJAX possible

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end

group :development do
  gem 'listen', '~> 3.3'
  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

# ALLOW CORS ONLY FOR DEV
gem 'rack-cors'

gem 'unicorn'

gem 'responders'

gem 'postmark-rails'

# gem 'bcrypt'

I would guess there might be something wrong with a path configuration but I do not know where to go from here, can anyone point me in the right direction?
