undefined method 'env' for nil:NilClass

Question

This is what my spec file looks like: spec/api/v1/projects_spec.rb

require "spec_helper"

describe "/api/v1/projects", :type => :api do
  context "projects viewable by this user" do
   it "JSON" do
   end
  end
end

It contained a lot more but I deleted a lot of lines in an unsuccessful attempt to find the error which goes like this:

Failure/Error: Unable to find matching line from backtrace
NoMethodError: undefined method `env' for nil:NilClass

This piece of code is from the "Rails 3 in Action" by Ryan Bigg. The only other file it includes is: spec/support/api/helper.rb

module ApiHelper
  include Rack::Test::Methods

  def app
   Rails.application
  end
end

RSpec.configure do |c|
  c.include ApiHelper, :type => :api
end

I've been trying to google the error for the past 1 hr and the closest thing that I found was this and as a result I deleted the code which used Devise::Test_Helpers. Sadly, its still not working.

Any help would be appreciated. Thank you so much.

You're still including Devise::TestHelpers somewhere. Check and see what "spec_helper" is loading.
