I\'m following Hartl\'s railstutorial.org and have arrived at 11.4.4: Image upload in production. What I\'ve done:
You may be missing a step which is to set your IAM policy if using an IAM user to configure your bucket.
Go to IAM console, select your user, go to the permissions tab
, click the attach policy
button and add administrator access
.
After that the error should go away and you can upload files with no problem ;)
