During the passage of Chapter 13, the Rails Tutorial encountered the inability to start downloading images on Heroku using CarrierWave, Fog and AWS S3. Every time I encounter the same error:

if Rails.env.production? CarrierWave.configure do |config| config.fog_provider = 'fog/aws' config.fog_credentials = { :provider => "AWS", :aws_access_key_id => ENV["S3_ACCESS_KEY"], :aws_secret_access_key => ENV["S3_SECRET_KEY"], :region => ENV["S3_REGION"] } config.storage = :fog config.fog_directory = ENV["S3_BUCKET"] config.cache_dir = "#{Rails.root}/tmp/uploads" end end Judging by the error, the problem must come from AWS. I tried to apply different rights to IAM users, including AmazonS3FullAccess and AdministratorAccess. I reviewed all the issues found on the SO, but absolutely nothing helped me, so I will be very grateful for any help.
