Scripts.Render throwing 'Object not set to an instance of an object' error

I am using visual studio 2019.
I have a problem which I haven't encountered before - in view, this line (just this line) is throwing error:
#Scripts.Render("~/scripts/scriptCommon")
I've checked bundles config:
ScriptBundle scriptCommon = new ScriptBundle("~/scripts/scriptCommon");
scriptCommon.Include("~/static/scripts/jquery-1.11.0.min.js");
scriptCommon.Include("~/static/scripts/bootstrap.min.js");
Both files are on the file system.
This bundle is also added to bundles with:
bundles.Add(scriptCommon);
(just like all the other bundles)
I don't understand why this error? What could be the reason?
Short error message:
System.NullReferenceException: Object reference not set to an instance of an object.

Try this, which worked in my system and project:
Open BundleConfig.cs. You should find it at the App_Start folder.
Then change the bundling for your specific script #Scripts.Render("~/scripts/scriptCommon"), from ScriptBundle scriptCommon = new ScriptBundle("~/scripts/scriptCommon"); to Bundle scriptCommon = new Bundle("~/scripts/scriptCommon");
I had a similar problem when upgrading Bootstrap from 4.5 version to 5.*
I set in public static void RegisterBundles(BundleCollection bundles) { ... } method, from:
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include("~/Scripts/bootstrap.js"));
to:
bundles.Add(new Bundle("~/bundles/bootstrap").Include("~/Scripts/bootstrap.js"));
Change ScriptBundle into just Bundle.

Issues with Razor helper methos. VS 2013 update 3. MVC 5.2.1

We are refactoring the MVC (version 5.1.2) project. I have a custom helper method written in C# to dynamically build HTML and is called from the view.
Now I moved all the code from C# into Razor.
I created a helper file called Header.cshtml under the App_Code directory and moved all the C# code into this helper class.
#helper ProHeader(object model) {
string tablType = model.GetType().GetProperty("table_type").GetValue(model, null).ToString();
var result = tablType.Split(new[] { "_" }, StringSplitOptions.RemoveEmptyEntries);
............................... HTML code goes here....................
}
I am getting the following error when I run the app.
[NullReferenceException: Object reference not set to an instance of an object.]

Unable to fix 'The object cannot be deleted because it was not found in the ObjectStateManager.' [duplicate]

This question already has answers here:
The object cannot be deleted because it was not found in the ObjectStateManager
(10 answers)
Closed 8 years ago.
I am getting the following error when I try to delete an object from the datase using LINQ.
The object cannot be deleted because it was not found in the ObjectStateManager.
Note: When I try to run the query directly from the database, the object is deleted.
Code where I am getting the error:
public void deleteStorage(CommonLayer.TblNewsStorage storageToDelete)
{
using(DBTicketSystemEntities e = new DBTicketSystemEntities())
{
e.TblNewsStorage.DeleteObject(storageToDelete);
e.SaveChanges();
}
}

Try sending the ID of the object you want to delete then query it inside your context instead of sending the whole object :
public void deleteStorage(int ID)
{
using(DBTicketSystemEntities e = new DBTicketSystemEntities())
{
//Like That
var selectedItem = e.TblNewsStorage.Where( t => t.ID == ID).FirstOrDefault();
e.TblNewsStorage.DeleteObject(selectedItem);
e.SaveChanges();
}
}

try below code:-
e.TblNewsStorage(storageToDelete).State = System.Data.EntityState.Deleted;
e.SaveChanges();
OR
e.TblNewsStorage.Attach(storageToDelete);
e.TblNewsStorage.Remove(storageToDelete);
e.SaveChanges();

You should check Newtonsoft.Json library version on that computer (also in GAC). Non-generic ToObject methods where introduced in November last year, so there is slight chance this causes problem.

constructor of a controller don't take a param mvc

why when i add a param for the constructor of the controller, I get an error.
this is my code:
public partial class RegistrationController : Controller
{
public RegistrationController(int i)

}
public ActionResult Index()
{}
}
the error is `Server Error in '/' Application.

If you insist the the constructor parameter you have to build your own ControllerFactory implementing the IControllerFactory interface and set it in the app start.
ControllerBuilder.Current.SetControllerFactory(new MyControllerFactory());

MVC will try to instantiate the controller specified in the route for each request by calling its default constructor.
From the looks of it, you want to hit a URL like: /registration/{someNumber}.
If this is the case, move the int id from the constructor to the action method:
public partial class RegistrationController : Controller
{
public RegistrationController()
{ }
public ActionResult Index(int i)
{
// do something
}
}
