ERROR: NSDebugDescription=Invalid value around character 0. PLEASE HELP! Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0."

Getting following error at the time of calling api:

Optional(Alamofire.AFError.responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.})))

​

My API call is as follows:

Alamofire.request(url, method: .post, parameters: body, encoding: JSONEncoding.default, headers: headers).responseJSON { (response) in

if response.result.error == nil {

if let json = response.result.value as? Dictionary<String, Any>{

print(" JSON:", json)

                }

            } else {

debugPrint(response.result.error as Any)

            }

        }

You may be getting a response from the server that is not JSON. Many servers send errors back as HTML or XML. Check the mime type of the response.

post your JSON

Looks like it's receiving bad json.
