Problem with Rails 7 App with Amazon S3 on Heroku

I have rails 7 with the Ruby 3.1.1 application, It's using Amazon S3 for storing images, I have added AWS credentials as well on the app. I have deployed the app to Heroku, ran the migration, and added all the environment variables on Heroku, but when I try to access the Heroku link, I get this error:

"missing credentials, provide credentials with one of the following options: (Aws::Sigv4::Errors::MissingCredentialsError)

  • :access_key_id and :secret_access_key
  • :credentials
  • :credentials_provider"

Has anyone ever had this kind of a problem? How did you correct it?

Storage.yml

test:
  service: Disk
  root: <%= Rails.root.join("tmp/storage") %>

local:
  service: Disk
  root: <%= Rails.root.join("storage") %>


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: <%= Rails.application.credentials.dig(:aws, :region) %>
  bucket: <%= Rails.application.credentials.dig(:aws, :bucket) %>

development.rb/production.rb

  config.active_storage.service = :amazon

EDITOR="code --wait" rails credentials:edit

aws:
  access_key_id: ******
  secret_access_key: *******
  region: *******
  bucket: *******

I have added also a RAILS_MASTER_KEY env var on Heroku but still I get an error.

For heroku to read the master key you need to run

heroku config:set RAILS_MASTER_KEY=cat config/master.key``
