Can upload but not delete image on Heroku using Paperclip and AWS S3

S3 credentials are configured correctly for Paperclip:

# production.rb (same in development.rb)
config.paperclip_defaults = {
  :storage => :s3,
  :path => 'photos/:id/:style/:filename',
  :s3_credentials => {
    :bucket => ENV['aws_bucket'],
    :access_key_id => ENV['aws_access_key'],
    :secret_access_key => ENV['aws_secret_key']
  }
 }

I do see the environment variables set in the Heroku UI, and I can upload photos just fine.

However when I try to destroy the given model on production, I get this error in the log:

This all works just fine locally too (obviously using a different S3 bucket). What's the issue? Why am I getting AWS::Errors::MissingCredentialsError just on production even though uploads work fine?

You probably want to make sure you're on the aws-sdk gem v1 and not aws-sdk v2. Logs make it look like you're on v1 ("AWS::") -- if you're on aws-sdk v2, paperclip won't work. Don't think thoughtbot is going to support it going forward, I recommend you look into direct upload to s3 using jquery-file-uploader (https://devcenter.heroku.com/articles/direct-to-s3-image-uploads-in-rails#pre-signed-post) -- Note that article does not show aws-sdk-v2 instructions. The answer linked below does use aws-sdk-v2:

Rails direct to S3 upload using aws-sdk gem and jQuery-File-Upload on heroku
