This is my first post on this topic so please be gentle, but I'm getting a Keyerror when running my app rakefile. Any ideas?

remote:        Paperclip is now compatible with aws-sdk >= 2.0.0.
remote:        If you are using S3 storage, aws-sdk >= 2.0.0 requires you to make a few small

remote:        * You must set the `s3_region`
remote:        * If you are explicitly setting permissions anywhere, such as in an initializer,
remote:        note that the format of the permissions changed from using an underscore to
remote:        using a hyphen. For example, `:public_read` needs to be changed to
remote:        `public-read`.

    Welcome to Stackoverflow and be more specific about your question. Avoid posting a bunch of error logs. Research a bit and then post the logs which describes your problem to get faster response. Commented May 24, 2016 at 15:34
  • Looks like the problem is in your configuration for your S3 bucket (KeyError: key not found: "S3_BUCKET_NAME"). Did you get your bucket name from your aws account and include it during configuration? Commented May 25, 2016 at 12:17
  • This is the reference to the S3 in the production.rb file. Is this where the details should be hardcoded? # Amazon Web Services 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'), Commented May 25, 2016 at 13:28
  • @Aiden I am running into the same issue, and I have all of this in my production.rb file. Any thoughts as to why it isn't recognizing it? if i run heroku config it has all of it listed there. and the set up works fine (things are being saved into S3). I just cant precompile any more assets now Commented Sep 23, 2016 at 15:20

You need to set S3_BUCKET_NAME environment variable on Heroku.

On CUI you can heroku config:set S3_BUCKET_NAME=name_of_bucket

On GUI you can go to your Heroku app's Settings tab, and Reveal Config Vars and save whatever variables you need.

I recommend setting variables on CUI, because I had an issue that some variables are somehow not loaded, and re-setting of variable on CUI solved problem.

I was having this issue for FB_API_KEY even though I had already set the config value using the Heroku Dashboard -> Settings GUI. When I pushed the values up from the command line the next 'git push heroku master' was able to precompile with no issue. Thank You!
