How do I fix this error NameError: uninitialized constant AWS

So I got this error: NameError: uninitialized constant which StackOverflow says means that it is unintentionally upgrading, but that cannot be, because my version is the highest, I have in the gem file: gem "aws-sdk-s3", require: false

Could it have to do with the initializer file? This is where in the build log it went wrong:

This is the aws.rb file:

AWS::S3::Base.establish_connection!(
    :access_key_id   => ENV['S3_KEY:'],
    :secret_access_key => ENV['S3_SECRET']
   )

This is on the Heroku side: enter image description here

I'm not allowed to embed images yet so there's the link only.

Okay, I changed the aws.rb file to this:

require 'aws-sdk'
AWS::S3::Base.establish_connection!(
    :access_key_id   => ENV['S3_KEY:'],
    :secret_access_key => ENV['S3_SECRET']
   )

And got this:

 Running: rake assets:precompile
       rake aborted!
       LoadError: cannot load such file -- aws-sdk

I changed the AWS gem to: gem 'aws-sdk'

and got this output from the build log failure instead:

Running: rake assets:precompile
       rake aborted!
       NameError: uninitialized constant AWS

This is part of my storage.yml file:

# Use rails credentials:edit to set the AWS secrets (as aws:access_key_id|secret_access_key)
amazon:
   service: S3
   #access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id) %>
  # secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key) %>
   region: us-east-1
   bucket: agrifood.bucket

After commenting out the aws.rb intializer file and changing the storage.yml to the below:

# Use rails credentials:edit to set the AWS secrets (as aws:access_key_id|secret_access_key)
amazon:
   service: S3
   #access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id) %>
   #access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id  => ENV['S3_KEY:']) %>
   access_key_id: ENV['S3_KEY:'])
   secret_access_key: ENV['S3_SECRET'])
   #secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key => ENV['S3_SECRET']) %>
   #secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key) %>
   #region: us-east-1
   region: eu-west-1
   bucket: agrifood.bucket

And adding the Active Storage build pack, I got this:

###### WARNING:
       We detected that some binary dependencies required to
       use all the preview features of Active Storage are not
       present on this system.
       
       For more information please see:
         https://devcenter.heroku.com/articles/active-storage-on-heroku

Most recently I changed the storage.yml to this:

amazon:
   service: S3
   #access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id) %>
   #access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id  => ENV['S3_KEY:']) %>
   access_key_id: ENV['S3_KEY:'])
   secret_access_key: ENV['S3_SECRET'])
   #secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key => ENV['S3_SECRET']) %>
   #secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key) %>
   #region: us-east-1
   #region: eu-west-1
   region: ENV['AWS_BUCKET_REGION'])
   bucket: agrifood.bucket
'''
Which still gave me this:

WARNING: Detecting rails configuration failed set HEROKU_DEBUG_RAILS_RUNNER=1 to debug

WARNING: 
   We detected that some binary dependencies required to
   use all the preview features of Active Storage are not
   present on this system.


I then changed it to this:

Aws.config.update({ region: 'eu-west-1', credentials: Aws::Credentials.new(ENV['S3_KEY:'], ENV['S3_SECRET']), })

S3_BUCKET = Aws::S3::Resource.new.bucket(ENV['S3_BUCKET'])


As per the advice to changed AWS to Aws I did what is just above, however, that didn't fix it.

Have you required the aws sdk before any usages of AWS (that can be done in an initializer)? Have you tried to remove require: false from the gemfile? – Mahmoud Sayed
@MahmoudSayed Which should I do first? – Fintan Moloney
I'm not sure but I see in document it uses Aws constant instead – Ninh Le
@FintanMoloney Try to remove require: false from Gemfile and re-run bundle install. – Mahmoud Sayed

try to make bundle install, it it does not help, share the file config/initializers/aws.rb with us, to understand the problem better. The error because you do not AWS in your application

I fixed this issue by changing the Gem to:

 gem 'aws-sdk-v1'

and remove: require 'aws-sdk'.

This worked for me. Thanks
