Paperclip::Errors::NotIdentifiedByImageMagickError - Rails app + Swift 2

Question

I am trying to upload a photo from a Swift 2 application, and I am getting Bad Request.

I am using:

• Amazon EC2
• Ruby on Rails
• Paperclip

I am executing this code:

Swift

func convertImageToBase64(image: UIImage) -> String {
   let imageData = UIImagePNGRepresentation(image)
   let base64Encoded = imageData!.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
   return base64Encoded
}

and then I send the info through a parameter:

let image_str = self.global.convertImageToBase64(self.global.compressForUpload(self.newMediaImage.image!, withHeightLimit:750, andWidthLimit:750))

parameters["spot[image]"] = "data:image/png;base64,\(image_str)"

notice that my headers are:

headers["Accept"] = "application/json"
headers["Content-Type"] = "multipart/form-data"
headers["Access-Control-Request-Method"] = "POST"
headers["Access-Control-Request-Headers"] = "X-Requested-With"

And I get this message error:

A piece of the image that my rails app receive would be:

Answer 1

It's working now. The solution was:

I just changed the version of the aws-sdk gem which was < 2 to gem 'aws-sdk', '>= 2.0.0' and it worked pretty well.

Besides that, I re-installed imagemagick on amazon ec2 and Rmagick.
