Download Paperclip to Heroku using S3

I'm sorry to rephrase the old pen, but I'm on my way and don't know where to go next. I am using Paperclip on Heroku and configured to download S3. I was able to get everything to work in my local development environment, but as soon as it starts up on Heroku I run into this error:

AWS::S3::Errors::PermanentRedirect (The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

      

        
        
        
      

    

I searched for this error and read the Heroku documentation and I believe everything is configured correctly. At first I thought my problems were related to having my bucket in the region s3-us-west-1.amazonaws.com

, but I'm not sure anymore.

Here are the relevant parts of my Heroku config:

AWS_REGION:                      us-west-1
S3_BUCKET_NAME:                  my-super-awesomely-amazing-bucket

      

        
        
        
      

    

From config / environment / production.rb file:

  config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
      :bucket => ENV['S3_BUCKET_NAME'],
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    } 
  }

      

        
        
        
      

    

My initialization paperclip.rb file:

if Rails.env.production? 
  Paperclip::Attachment.default_options[:url] = ':s3_domain_url'
  Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'
  Paperclip::Attachment.default_options[:s3_host_name] = 's3-us-west-1.amazonaws.com'
end

      

        
        
        
      

    

And my paperclip config from the corresponding model:

has_attached_file :document,
:styles => { },
:default_url => "/image_styles/:style/missing.png"

      

        
        
        
      

    

So ... what am I doing wrong here? At this point, I'm sure I missed something obvious, but I'm stumped as to where to go from here. I feel like I have diligently configured everything and yet the error PermanentRedirect

keeps growing.
