I followed this instruction "https://devcenter.heroku.com/articles/direct-to-s3-image-uploads-in-rails" to implement the "Upload file to S3 directly using Jquery-FileUpload"
It works perfectly in my localhost, but somehow it doesn't work on CircleCi . It always jump to the "fail" callback of Jquery-Fileupload without any specific error message
I already config the CORS configurations on AWS to allow "*" origin , which should works fine on all hosts ( and it does work on my localhost and my production server, but it still doesn't work on Circle CI )
Anybody experienced with it please guide me through this, biggest appreciation for any kind of help ( i can buy you a beer if you're in Vietnam :) )
Best regards
