Action can't be found - ruby-on-rails

Apologies for vague title. I am following https://www.railstutorial.org/book/beginning#cha-beginning tutorial to learn RoR on cloud9. I have made the changes in my controller as listed in chapter 1, heading 1.4
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
def hello
render text: "hello, world!"
end
end
and my routes.rb file
Rails.application.routes.draw do
root 'application#hello'
end
But when i restart the server, I gett error

I have already tried root to: 'application#hello' and it still didn't work

The application controller is not for defining actions. This is the base controller where likely other controllers should inherit behavior/properties from. You should create another controller and define hello there.
using generator
rails g controller Welcome hello
routes file
root Welcome#hello
get 'hello' => 'welcome#hello'
app/controllers/welcome_controller.rb
class WelcomeController < ApplicationController
def hello
end
end

Thanks all. The problem is with Cloud9 IDE. I did save the application_controller after creating the hello method but IDE wasn't saving it untill i explicitly clicked on File > Save. I figured it out when i cat application_Controller.rb and noticed that hello method doesn't exist there.

I was using webrick locally. I just added gem 'puma' to the group :development of my Gemfile and that fixed the problem.

Moved a Rails app to EC2 and now my file uploads get a Encoding::UndefinedConversionError ("\xC3" from ASCII-8BIT to UTF-8) error

I've got a Rails app that has been live for over a year with no issues, running on a custom Ubuntu/Nginx/Puma setup.
Because of various issues with the hosting company, I moved the app over to EC2 this weekend - using ElasticBeanstalk on their Nginx/Puma/Ruby2.2 stack.
Everything is working fine - apart from file uploads.
The app itself uses the Paperclip gem for handling attachments - the actual files are only held momentarily in Paperclip, before being uploaded to a file-server controlled by my client (the very first version used S3 for storage, but now it uploads, attaches the "Job-Sheet" to the Job and then immediately uploads the "Job-Sheet" to the file-server).
As I say, this was all working fine on my old server. But now, on EC2, I'm getting a Encoding::UndefinedConversionError ("\xC3" from ASCII-8BIT to UTF-8) error.
The job sheet itself can be an Excel file or a CSV. It is defined as follows:
class Job < ActiveRecord::Base
...
has_attached_file :job_sheet
validates_attachment_file_name :job_sheet, matches: [/csv\Z/, /xls\Z/, /xlsx\Z/]
validates_attachment_presence :job_sheet
...
end
The controller looks like this:
class JobsController < ApplicationController
...
def create
#job = services['creates_job'].create_job job_params, session: current_session
redirect_to jobs_path
rescue ActiveRecord::RecordInvalid
...
end
...
end
The jobs_params does the StrongParams thing of permitting the parameters as required.
And the CreatesJob service object looks like:
def create_job params, session: nil
...
job = services['jobs'].create! params.merge(code: code)
...
end
So apart from the fact that the actual logic is in a separate "CreatesJob" class, there's nothing unusual going on - pretty much a standard Rails/Paperclip upload situation.
However, some uploads are failing, with the following in the production log:
I, [2016-03-22T10:12:58.701172 #23116] INFO -- : Started POST "/jobs" for 80.0.249.70 at 2016-03-22 10:12:58 +0000

The other answers related to this error all seem to be about forcing the encoding of the file. But the issue here seems to be 1) sometimes it's a binary (xls) and sometimes text (csv) so I can't go around mangling it and 2) the exception is in ActionDispatch; so looks like it's happening before I get to see the upload.
Any ideas what's going on and what I can do to fix it?
UPDATE: I can now reproduce the issue consistently. If I upload an XLSX file with an English filename, the upload works OK, if it's an XLSX file with Spanish accented in the filename, the upload fails as shown above.
The line in question is #original_filename.encode!(Encoding::UTF_8) in action_dispatch/http/upload.rb - however, the filename should be valid unicode, but it's obviously getting mangled in transit somewhere.

Multiple syntax errors out of the blue with ruby on rails project

I'm not a ruby on rails developer so this might be a menial fix. The friend I'm working on with this project is currently unavailable and was hoping someone could help me resolve this issue that sprang up randomly after reboot my VM. No changes to any files, it was just working and after reboot it wasn't. Tried googling to no avail.
Here is the full post from the console:

New Rails project internal server error

I'm using Ubuntu 15.04. I installed RVM, Ruby 2.2 and Rails 4.2.2. When I create a new project doing rails new blog, when I start the server I get a plain text message saying "Internal Server Error". What's weird is that it's in plain text format.
I can't figure out why. Here's the error log:
