Function call:

func getdata() {
        
        let baseURL = “my url“
        let token = “my token”
        
        var urlRequest = URLRequest(url: URL(string: baseURL)!)
        urlRequest.addValue("bearer \(token)", forHTTPHeaderField: "Authorization")
        urlRequest.httpMethod = "GET"
        
        let task = URLSession.shared
        task.dataTask(with: urlRequest) { data, response, error in
            
            
            if (error == nil && data != nil && data?.count != 0) {
                let decoder = JSONDecoder()
                do {
                    let result = try decoder.decode(Root.self, from: data!)
                    print(result.result.workStreams.workGroupObjects)
                } catch let error {
                    debugPrint("error occurred while decoding: \(error)")
                } 
            } else {
        return 
            }                                   
        }.resume()
        
    }

error in the console : "error occured while decoding: keyNotFound(CodingKeys(stringValue: "result", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"result\", intValue: nil) (\"result\").", underlyingError: nil))"

Models: 

// MARK: - Root
struct Root: Decodable {
    let result: Result
    let status: Status
}

// MARK: - Result
struct Result: Decodable {
//    let reportList: [Any?]
    let userLayOut: String
    let workStreams: WorkStreams
}

// MARK: - WorkStreams
struct WorkStreams: Decodable {
    let workGroupObjects: String
//    let ownerWorkGroupList: [Any?]
}

// MARK: - Status
struct Status: Decodable {
    let number: Int
//    let message: NSNull
}

am i missing something in my models? if yes what is it??

JSON: 

{
    "result": {
        "ReportList": [],
        "UserLayOut": “ This is a string ”,
        "workStreams": {
            "workGroupObjects": “ This is also a string ”,
            "OwnerWorkGroupList": []
        }
    },
    "Status": {
        "Number": 0,
        "Message": null
    }
}

can someone please explain me what should i am i doing wrong?
