I always got 'objectmapper failed to serialize response' when parsing error response about alamofireobjectmapper HOT 9 CLOSED

Hello dude!, The same thing happening to me as well. When I run your code for single object it is giving
Error Domain=com.alamofire.error Code=-6004 "ObjectMapper failed to serialize response." UserInfo={NSLocalizedFailureReason=ObjectMapper failed to serialize response.}

let URL = "https://raw.githubusercontent.com/tristanhimmelman/AlamofireObjectMapper/d8bb95982be8a11a2308e779bb9a9707ebe42ede/sample_json"
Alamofire.request(.GET, URL).responseObject("data") { (response: Response<WeatherResponse, NSError>) in

let weatherResponse = response.result.value
print(weatherResponse?.location)

if let threeDayForecast = weatherResponse?.threeDayForecast {
    for forecast in threeDayForecast {
        print(forecast.day)
        print(forecast.temperature)           
    }
}

}

So please help me out of from this.

@JayachandraA bad news, I dogged into the code and this library have just written an extension with own serializer and fixed error message for us.

I think the proper way is clone this repository and edit the serializer yourself.

from alamofireobjectmapper.

ObjectMapper doesn't yet support specific error messaging when parsing errors occur. This is why this extension simply reports the same error.

@JayachandraA, looking at the sample you are trying to run, I can see the error by looking at the JSON response linked. You are trying to deserialize using data as a keypath but data isn't in the JSON response. Try again but omit the keypath.

@tristanhimmelman @macbaszii thanks guys for your response. finally I found the solution.

from alamofireobjectmapper.

@JayachandraA What was your solution ? Could you share to us ?

from alamofireobjectmapper.

@macbaszii I just assigned empty values when I'm declaring optional properties
like this
var name: String? = ""
var desc: String? = ""
var coverURL: NSURL? = nil
var membersAmount: Int? = 0
var sportName: String? = ""

I have set the initial values to nil regarding @JayachandraA 's solution. before setting them to nil, i gave them values of "" (if they are string), 0(if they are int), [""](string array), [0](int array)
