I always got 'objectmapper failed to serialize response' when parsing error response

[macbaszii]

import Foundation
import ObjectMapper
import AlamofireObjectMapper

private let NameKey = "name"
private let DescriptionKey = "description"
private let CoverURLKey = "cover_url"
private let MembersAmountKey = "members_count"
private let SportNameKey = "sport_name"
private let PagePolicyKey = "policy"

class Tribe: Mappable {
    var name: String?
    var desc: String?
    var coverURL: NSURL?
    var membersAmount: Int?
    var sportName: String?
    var policy: ObjectPolicy?
    required init?(_ map: Map){

    }

    func mapping(map: Map) {
        name <- map[NameKey]
        desc <- map[DescriptionKey]
        coverURL <- (map[CoverURLKey], URLTransform())
        membersAmount <- map[MembersAmountKey]
        sportName <- map[SportNameKey]
        policy <- map[PagePolicyKey]
    }
}

this is my class and I just used simply -responseObject object method in APIClient
Thank in advance.

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.

[tristanhimmelman]

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.

[macbaszii]

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

[JayachandraA]

@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? = ""

@tristanhimmelman Hello I am having the same issue. I'll really appreciate if one can help me immediately, i really need a quick response.
Here is an example returning json
->
[
{
"eventdescription": "event2",
"participantid": "{7,2,3,NULL,NULL,NULL,NULL,NULL,NULL,NULL}",
"mainphotoid": 3,
"photosid": "{7,3,2,NULL,NULL,NULL,NULL,NULL,NULL,NULL}",
"ownerid": 2,
"invitationlist": "{7,4,6,8,NULL,NULL,NULL,NULL,NULL,NULL}",
"privilligeId": "{7,3,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}",
"eventid": 2,
"eventdate": "2016-10-05 00:00:00",
"eventitle": "Come on first2"
},
{
"eventdescription": "asd",

"eventitle": "asdasd"
},
null,

Here is my class to create mappable
->

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)

This is my request
->

This is what i get when i print the responseString

Success: true
Response String: Optional("[{"eventdescription":"event2","participantid":"{7,2,3,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","mainphotoid":3,"photosid":"{7,3,2,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","ownerid":2,"invitationlist":"{7,4,6,8,NULL,NULL,NULL,NULL,NULL,NULL}","privilligeId":"{7,3,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","eventid":2,"eventdate":"2016-10-05 00:00:00","eventitle":"Come on first2"},{"eventdescription":"asd","participantid":"{9,1,2,3,NULL,NULL,NULL,NULL,NULL,NULL}","mainphotoid":2,"photosid":"{1,2,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","ownerid":2,"invitationlist":"{2,4,7,8,NULL,NULL,NULL,NULL,NULL,NULL}","privilligeId":"{1,2,3,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","eventid":3,"eventdate":"2016-10-05 00:00:00","eventitle":"asdas"},{"eventdescription":"UpdateasddddLet's starts","participantid":"{9,1,2,3,NULL,NULL,NULL,NULL,NULL,NULL}","mainphotoid":2,"photosid":"{1,2,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","ownerid":3,"invitationlist":"{2,4,7,8,NULL,NULL,NULL,NULL,NULL,NULL}","privilligeId":"{1,2,3,NULL,NULL,NULL,NULL,NULL,NULL,NULL}","eventid":4,"eventdate":"2016-10-05 00:00:00","eventitle":"asdasd"},null,null,null,null,null,null,null]")

I am really desperate here i just hope that somebody can help me immediately

I have used swiftyJson and could handle the nulls.
