PaperClip is not running on the local host - Ruby on Rails - ruby-on-rails

Question

I created a site for storing rails photo posts. Pictures are saved in AWS. Sites works fine - photos go to AWS and display on the site: https://pp-obrazkowo.herokuapp.com/pins
The problem is, entries are not showing up locally - http://127.0.0.1:3000/pins.
They will throw an error: missing required: bucket option
The site stopped working properly after configuring the paperclip service.
In addition, there is an error in the supervisor:
ArgumentError in Pins # index

I think you may have made the same mistake I did before. In your development.rb file, do not edit the text to add your specific S3 keys. Just copy-paste the text directly as is listed in the tutorial.
#development.rb
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['AWS_BUCKET'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
Then, set the environmental variables AWS_BUCKET, AWS_ACCESS_KEY_ID, and AWS_SECRET_ACCESS_KEY as described by the author of the dev center article.
Btw, I'm not sure why you are using PaperClip(deprecated gem) on Rails 6. Rails 6 has ActiveStorage library to do the same thing perfectly.
