Alamofire.AFError.ResponseValidationFailureReason.unacceptableStatusCode(500)

Question

I'm working on Alamofire and I am trying to post a request to the server like this:

func sendRequest () {

    print("fire now----------------------------------------------")

    let parameters: Parameters = ["user": "001", "name": "josh"]

    print(parameters)
   let a = Alamofire.request("http://120.77.252.96:8388/", method: .get, parameters: parameters, encoding: URLEncoding.default).validate(statusCode: 200..<500).responseJSON(completionHandler: {responds in
        switch responds.result {
        case .success(let value):
            let json = JSON(value)
            print("JSON: \(json)")
        case .failure(let error):
            print(error)
        }}
    )
    print(a)

}

But I constantly get errors like this:

Alamofire.AFError.ResponseValidationFailureReason.unacceptableStatusCode(500)

and when I check the server side, it seems that the body of the request is empty.
Can anyone help me with this? Thanks so much!

I had the same problem my friend and I resolved it by changing the status code from

validate(statusCode: 200..<500)

to

validate(statusCode: 200..<600)

I'm new to Alamofire so I cannot give you an explanation to why or how it works or what the error means.
