This error occur when i try to save the image.

config/initializers/carrierwave.rb

CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS',
:aws_access_key_id => 'XXXXX',
:aws_secret_access_key => 'YYYYY',
:region => 'us-east-1',
:host => 's3.example.com',

}

config.fog_directory = 'My_bucket_name'
config.fog_public = false
config.fog_attributes = {'Cache-Control'=>"max-age=#{365.day.to_i}"}

end

i am using figaro.gem

config/application.yml

Gemfile

gem "figaro"

app/uploaders/picture_uploader.rb

class PictureUploader < CarrierWave::Uploader::Base

storage :

fog
def store_dir
'uploads/data'
end

end

i followed this site http://blog.thefirehoseproject.com/posts/switching-carrierwave-to-use-s3-with-heroku-and-localhost/ and didn’t made any changes other configurations.

i have deployed my application to heroku. i want to upload images/videos to that application. can anyone help or suggest me to how to upload images/videos to heroku with using carrierwave.

Thanks advance

You shouldn’t be setting that host or endpoint option ( you’d only use those if you were using a custom file storage service that speaks the S3 protocol, e.g. eucalyptus walrus)
