Custom Environment in rails 2.3 - Fedena - ruby-on-rails

I have created a custom environment in rails 2.3(Fedena) by copying the file content under config/environment/production.rb and also added env key in database and other ymls. Db creation and migration was successful on this custom environment. But, I am unable to access site after server launch in custom environment. Starting server doesn't throw any error but while accessing site I receive an error
NoMethodError (undefined method `+' for nil:NilClass)
I am not getting this error on other environments.
The stack trace is below for the error:

I also tried running sudo chmod -R 1777 tmp/ but got the same results.
I also had a lot of problems with vagrant, I think is a good tool but still had many bugs. Every time I had problems with
vagrant up
I just restart my computer.

end
but it doesn't work.

Maybe there is an error in your API somewhere. The following should work (tested with Grape 0.13.0):
module Api
class API < Grape::API
rescue_from Grape::Exceptions::ValidationErrors do |e|
error! e.message, 404
end
resource '/avatars' do
params do
requires :avatar, type: Rack::Multipart::UploadedFile
end
post '/' do
{
filename: params.avatar.filename,
file_type: params.avatar.type
}
end
end
end
end
Also, if you define a rescue_from :all block, be sure to do it as the last block. By the way, Grape has a pretty good documentation.

Rails app starts but Errors

My Rails app starts but gives me a No Method error. I'm not sure what method is apparently being called on something which doesn't. It can;t be a certain site page as it's happening on every url I try to visit. Anyone able hint where it's failing?

undefined method `[]' for nil:NilClass
I'm sure you quite beyond this but just to chime in, I had the same error. I commented out the better_errors gem, re-bundled, reran my app, and found I was getting an error elsewhere. I don't know why better_errors was unable to handle it but once I fixed that other error, I re-enabled better_errors and everything was back to normal.
It's odd b/c I haven't had any problems with the gem before. I love it.

I've tried stripping all symbols out of that string, but no joy - same issue. Any idea what might be going wrong here? I've literally copied & pasted from the book, so I don't think it's a typo. Could possibly be a redis issue (I'm unfamiliar with it), but it seems to be working fine.
Any ideas appreciated
In gem file declare
gem 'yajl-ruby'
It is used to Parse and encode multiple JSON objects to and from streams or strings continuous.
And require 'yajl/json_gem'
in config/application.rb
