responseJSON getting no response

I am using Alamofire to try and put an image on image shack server using the image shack API. I am not getting a response back and get the error:

FAILURE: Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0.

I have highlighted where the error is referring too in the code also:

        let imageName = "pano.jpg"
        let postImage = UIImage(named: imageName)
        let urlStr = "https://post.imageshack.us/upload_api.php"
        let theUrl:NSString = urlStr.stringByRemovingPercentEncoding!
        let url = NSURL(string: theUrl as String)!
        let imgData = UIImageJPEGRepresentation(postImage!, 0.2)!
        let keyData = "0345CHKMad115dd32980b363be5f2d34731b8110".dataUsingEncoding(NSUTF8StringEncoding)!
        let keyJSON = "json".dataUsingEncoding(NSUTF8StringEncoding)!


Alamofire.upload(.POST, url, multipartFormData: { MultipartFormData in

                MultipartFormData.appendBodyPart(data: imgData, name: "fileupload", mimeType: "image/jpg")
                MultipartFormData.appendBodyPart(data: keyData, name: "key")
                MultipartFormData.appendBodyPart(data: keyJSON, name: "format")

            }) {encodingResult in

                switch encodingResult {
                case .Success(let upload, _, _):
                    upload.responseJSON(completionHandler: { response in

                        print(response) //ERROR HERE
                        guard let data = response.result.value
                            else{
                                print("Request failed with error data)")

                            return
                        }

                        if let info = data as? Dictionary<String, AnyObject> {
                            if let links = info["links"] as? Dictionary<String, AnyObject> {
                                if let imgLink = links["image_link"] as? String {
                                    print(imgLink)
                                }
                            }
                        }
                    })

I am completely lost what this problem means any help would be great.

   switch encodingResult {
                    case .Success(let upload, _,_):
                        upload.responseJSON(completionHandler: {response in

                            if let data = response.result.value as? Dictionary<String, AnyObject>{

                                if let links = data["links"] as? Dictionary<String, AnyObject> {
                                    if let imgLink = links["image_link"] as? String {
                                        print(imgLink)
                                    }
                                }
                            }


                        })
                    case .Failure(let error):
                        print(error)
                    }

Try this, before passing your url into the function do:

//Convert the NSURL to a NSString
let urlString:NSString = url.absoluteString() as! NSString

//Remove Percent Encoding
let theUrl:NSString = urlString.stringByRemovingPercentEncoding()

//Place Back into NSURL
let newUrl = NSURL(string:theUrl)

And pass newUrl instead of url. It would be better to do this before instantiation of the original url, but try that and see if that helps.

EDIT

try this too where you are having the issue:

var jsonError:NSError?
let json = NSJSONSerialization.JSONObjectWithData(response, options: nil, error: &jsonError) as NSDictionary {

    print(json)
}
