Post Api Error - Value cannot be null

Question

Hi

 

I am getting this error -

 

{ "Message": "An error has occurred.", "ExceptionMessage": "Value cannot be null.\r\nParameter name: entity", "ExceptionType": "System.ArgumentNullException", "StackTrace": " at System.Data.Entity.Utilities.Check.NotNull[T](T value, String parameterName)\r\n at System.Data.Entity.DbSet`1.Add(TEntity entity)\r\n at ProjectManagement.Controllers.EmployeesController.PostEmployee(Employee employee) in C:\\Users\\jagji\\documents\\visual studio 2015\\Projects\\ProjectManagement\\ProjectManagement\\Controllers\\EmployeesController.cs:line 142" }

 

Below values i entered in PostMan -

 

[ { "Id": 10, "Name": "Mark 10", "DepartmentId": 1, "Email": "[email protected]", "Active": "Y", "Gender":"Male" }]

public partial class Employee {
  public int ID {
    get;
    set;
  }
  public string Name {
    get;
    set;
  }
  public string Email {
    get;
    set;
  }
  public string Gender {
    get;
    set;
  }
  public Nullable < int > Salary {
    get;
    set;
  }
  public Nullable < int > DepartmentId {
    get;
    set;
  }
  public string Active {
    get;
    set;
  }
  public Nullable < System.DateTime > CreatedOn {
    get;
    set;
  }
  public Nullable < System.DateTime > UpdatedOn {
    get;
    set;
  } //public Department Department { get; set; } public virtual Department Department { get; set; } }

Thanks
