Alamofire httpBody show 500 statusCode in swift 5

Question

I am using Alamofire 5. I have put the parameters to httpbody. I have run it in Postman, and it is working fine. My body parameters are below.

{
"user_id": "user_id",
"username": "user_name",
"password": "pass",
"token": "",
"type_id": 100,
"country_id": 1,
"language_id": 1,
"customer_id": 1,
"parent_user_id": "",
"profile": {}
 }

I have used below code to put the request using Alamofire 5. Here is the code:

func change_password() {

let headers: HTTPHeaders = [
    "Content-Type": "application/json",
    "YumaSession": Global_Variable.globalValue.session_id
]
let parameters:Parameters = [
    "user_id": "user_id",
    "username":  "username",
    "password": txtPassword.text!,
    "token": "",
    "type_id": 100,
    "country_id": 1,
    "language_id": 1,
    "customer_id": 1,
    "parent_user_id": "",
    "profile": []
]

AF.request( url,method: .put,parameters: parameters,encoding: URLEncoding.httpBody,headers: headers).responseJSON{ response in

    switch response.result {
    case .success(let responseData):
        print("responseData-->",response.response!.statusCode)
    case .failure(let error):
        print("error--->",error)
    }
    }
   }

Above code returns 500 status code. What is wrong above the code?

You can tell POSTMAN to generate the equivalent request in CURL and use feature in Alamofire to print the request as a CURL one (cf. there https://stackoverflow.com/questions/53637437/alamofire-with-d/53637821#53637821) and compare the two codes. You'll be able to spot a difference. But `URLEncoding.httpBody`, as URLEncoded? Or JSONEncoded? — Larme, Dec 31 '19 at 16:13
The `profile` field is a dictionary in the postman body and an array in your AF parameters. Also is the server telling you why it’s returning 500 in the response body? — Warren Burton, Dec 31 '19 at 16:16

parameters.profile is defined with an array literal instead of an dictionary one. Fixed code below.

let parameters:Parameters = [
    "user_id": "user_id",
    "username":  "username",
    "password": txtPassword.text!,
    "token": "",
    "type_id": 100,
    "country_id": 1,
    "language_id": 1,
    "customer_id": 1,
    "parent_user_id": "",
    "profile": [:]
]
