Issue Report:

2. Expected behaviour:
3. Console logs (http://blog.getpostman.com/2014/01/27/enabling-chrome-developer-tools-inside-postman/ for the Chrome App, View->Toggle Dev Tools for the Mac app):

I want to attempt a post. I get this error.

I get more information here:

An unhandled exception occurred while processing the request.

InvalidOperationException: ‘Microsoft.AspNetCore.Mvc.MvcOptions.InputFormatters’ must not be empty. At least one ‘Microsoft.AspNetCore.Mvc.Formatters.IInputFormatter’ is required to bind from the body.

Microsoft.AspNetCore.Mvc.ModelBinding.Binders.BodyModelBinderProvider.GetBinder(ModelBinderProviderContext context)

The C# code is
[Route(«api/property»)]
public class PropertyController : BaseSirController
{
[HttpPost(«{contractId}/saveproperty»)]
public IActionResult SaveProperty(int contractId, [FromBody] PropertyContractDto property)
{
…

Я создаю API, используя flask для сети
у меня уже есть база данных, и запрос GET работает, но когда я пытаюсь выполнить POST, он дает мне эту ошибку

500 INTERNAL SERVER ERROR

Это код, который я написал

#User_schema
class UserSchema(ma.Schema):
 class Mata:
  fields = ('id', 'name', 'Email', 'Pass', 'Phone', 'Department', 'Major')

#init_schema
user_schema = UserSchema()
users_schema = UserSchema(many=True)

#create user
@app.route('/user', methods=['POST'])
def add_User():
 #id = request.json['id']
 name = request.json['name']
 Email = request.json['Email']
 Pass = request.json['Pass']
 #Phone = request.json['Phone']
 Department = request.json['Department']
 Major = request.json['Major']

 new_user = User(name, Email, Pass, Department, Major)
 db.session.add(new_user)
 db.session.commit()

 return user_schema.jsonify(new_user)

Это запрос, который я добавил на почту человека

{
    "name": "User 1",
    "Email": "User1@.com",
    "Pass": "qq1",
    "Phone": "0551",
    "Department": "IT 1",
    "Major": "IT 1"
}

Я также использую локальный сервер
я посмотрел на другие ссылки, и все просят журналы, и если я не ошибаюсь, я думаю, что я получаю их от

View > Developer > Show DevTools > Console

И это скриншот журнала: (я думаю)

В чем именно проблема я не понимаю

После добавления ошибки определения:
