Receive S3::Error::SignatureDoesNotMatch by using Paperclip with “s3” on Heroku

I am working with Paperclip and AWS and can successfully get the upload to work on my local host. The problem I run into is when I upload the app to Heroku I get:

AWS::S3::Errors::SignatureDoesNotMatch (The request signature we calculated does not match the signature you provided. Ch

eck your key and signing method.)

Locations.rb

has_attached_file :photo,
                :styles => { :thumb => "150x150#", :medium => "200x200#", :small => "50x50"},
                :path => ":attachment/:id/:style.:extension",
                :s3_domain_url => "adsimgstore.s3.amazonaws.com",
                :storage => :s3,
                :s3_credentials => S3_CREDENTIALS,
                :bucket => 'adsimgstore',
                :s3_permissions => :public_read,
                :convert_options => { :all => "-auto-orient" }

s3 initialize

# initializers/s3.rb
if Rails.env == "production"
 # set credentials from ENV hash
 S3_CREDENTIALS = { :access_key_id => ENV['S3_KEY'], :secret_access_key => ENV['S3_SECRET'],   :bucket => "adsimgstore"}
else
  # get credentials from YML file
  S3_CREDENTIALS = Rails.root.join("config/s3.yml")
end

I have followed the Heroku tutorial https://devcenter.heroku.com/articles/s3 and added all keys

Any suggestions?

  • check if your environment variables match

if you followed the heroku tutorial your environment variables would be AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.

run heroku config to check your env variables.

  • no :bucket in Credentials

You put the :bucket option in the S3_CREDENTIALS-hash in the initializers/s3.rb file. the bucket-option doesn't belong here - you already set it in the has_attached_file method.
