ERROR: ServiceError - Failed to deploy application. on ElasticBeanstalk - ruby-on-rails

Question

So, I am launching my app with Elasticbeanstalk and I am using Ruby on Rails for my app. However, when I ran the command "eb deploy {name}", it showed me the error
Creating application version archive "app-4f49-180904_151051".

However, I have check my gemfile, and did not see Autoprefix of any kind. I hope I am providing enough info, if not, please guide me in providing more details and finding an answer for this. Thank you in advance.

Same issue–fixed it by uncommenting mini-racer worked for me, like #KedarnagMukanahallipatna suggested above.
Change From
# Gemfile
# gem 'mini_racer', platforms: :ruby
Change To
# Gemfile
gem 'mini_racer', platforms: :ruby
