Problem with rest assured request body parameters "value_error.missing"

Question

I am trying to pass request body parameters in rest assured request, but it returns me with is very frustrating I am trying different ways I try with String like JSON format but is not working also always same error. Error message value_error.missing for all body parameters.

   value_error.missing
{
  "detail": [
    {
      "loc": [
        "body",
        "username"
      ],
      "msg": "field required",
      "type": "value_error.missing"
    },
    {
      "loc": [
        "body",
        "password"
      ],
      "msg": "field required",
      "type": "value_error.missing"
    }
  ]
}

The test code:

public Response login(String username, String password, String proxy) {
    //String user = "{\"username\":\"" + username + "\",\"password\":\"" + password + "\",\"proxy\":\"" + proxy + "\"}";
    Map<String, String> user = new HashMap<>();
    user.put("username", username);
    user.put("password", password);
    user.put("proxy", proxy);

    Response response = given()
            .headers(httpHeaderManager())
            .body(user)
            .spec(urlUser)
            .post("/auth/login")
            .then()
            .extract().response()
    
    
    return response;
    
}

JSONObject jsonObj = new JSONObject();
jsonObj.put("username", username);
jsonObj.put("password", password);
jsonObj.put("proxy", proxy);

RequestBody body = RequestBody.create(jsonObj.toString(), MediaType.parse("application/json; charset=utf-8"));

Response response = given()
        .headers(httpHeaderManager())
        .body(body)
        .spec(urlUser)
        .post("/auth/login")
        .then()
        .extract().response()

This should work
