`fetch': key not found: "S3_BUCKET_NAME" (KeyError)

Question

I am using Spree 3.1. To use Heroku, I need AWS S3 tp store pictures. Spent so much time with KeyError both local and Heroku.

Answer 1

And like to share here:

1. In AWS S3 document to create IAM USER for ID and access_key_id and secret_access_key. To make it work, I need to create profile and set admin permission.

2. Only paste this in needs environment eg: config/environments/production.rb and development.rb

    config.paperclip_defaults = {
      storage: :s3,
      s3_credentials: {
      bucket: ENV.fetch('S3_BUCKET_NAME'),
      access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'),
      secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'),
      s3_region: ENV.fetch('AWS_REGION'),
      }
     }
   

   Do not replace the value. Instead For Heroku:

   heroku config:set S3_BUCKET_NAME=your-bucket-name AWS_ACCESS_KEY_ID=your-access-key-id AWS_SECRET_ACCESS_KEY=your-secret-access-key AWS_REGION=your-region
   

And for local: We add values in .env

    $ cat .env
     S3_BUCKET_NAME=your-bucket-name-development
     AWS_ACCESS_KEY_ID=your-access-key-id
     AWS_SECRET_ACCESS_KEY=your-secret-access-key

Don't "quote" those values
