Enum element cannot be referenced as an instance member

I am creating an API layer using Moya and keep getting the above error for the target .updateMyWeightGoal

when I make a request for the endpoint.

    goalAPI.request(target:  .updateMyWeightGoal(weightGoalData: goalInfo),  success: { (response) in
        //
    }){ (response: [String : Any]) in
        print(response)
    }

      

        
        
        
      

    

I created another Moya API of the same type and call it using the same goalAPI

one and it works fine.

Any ideas that might be causing this problem

For reference: class definition for type weightGoalData

class UpdatedWeightGoalInfo: Mappable {

var consumerUserID: Int?
var height: String?
var weight: String?
var goalWeight: String?

init() {

}

convenience init(userId: Int, weightGoalData: WeightGoalResponse) {
    self.init()
    consumerUserID = userId
    height = "\(weightGoalData.currentHeight)"
    weight = "\(weightGoalData.currentWeight)"
    goalWeight = "\(weightGoalData.goalWeight)"
}

required init?(map: Map) {
}

func mapping(map: Map) {
    consumerUserID <- map["consumerUserId"]
    height <- map["height"]
    weight <- map["weight"]
    goalWeight <- map["goalWeight"]
}
}

      

        
        
        
      

    

And the API definition:

enum GoalSettingAPI: AccessTokenAuthorizable {

  case updateMyWeightGoal(weightGoalData: UpdatedWeightGoalInfo)
}

extension GoalSettingAPI: TargetType {
var parameterEncoding: ParameterEncoding {
    switch self {
    default:
        return JSONEncoding.default
    }
}

var baseURL: URL { return URL(string: appBaseURL + "*hidden*/")! }
var path: String {
    switch self {
    case .updateMyWeightGoal(_):
        return "updateMyWeightGoal"
    }
}

var method: Moya.Method {
    switch self {
    case .updateMyWeightGoal(_):
        return .post
    }
}

var parameters: [String: Any]? {
    switch self {
    case .updateMyWeightGoal(let weightGoalData):
        return weightGoalData.toJSON()
    }
}

var sampleData: Data {
    switch self {
    default:
        return Data()
    }
}

var task: Task {
    switch self {
    default:
        return .request
    }
}

var shouldAuthorize: Bool {
    switch self {
    default:
        return false
    }
}
}
