MVC5 Object reference not set to an instance of an object on Scripts.Render


I'm using Asp.net MVC5 and haven't encountered such this ambiguous error since 4 years working with Microsoft MVC platform! The error occurs in Manage page in default MVC5 template. here in line 26 at the _layout.cshtml file:

Line 24:     <![endif]-->
Line 25: 
Line 26:     @Scripts.Render("~/js/intf")
Line 27:     <script>
Line 28:         if (document.documentMode === 10) {

The Stack Trace says:

Edit: As you wanted the bundling code, I placed one of them here:

bundles.Add(new ScriptBundle("~/js/intf").Include(//first internal scripts
                "~/js/jquery*",
                "~/js/modernizr.js",
                "~/js/ie-prototype-polyfill.js",
                "~/js/prettyPhoto.js"));

NOTE: If I commentize the error lines (style/script bundling lines) The error will be @ViewBag.Title as the new error! I think the Razor view Engine got into trouble here, since it can't instantiate the view's codes requirements, But Why??

I know that some errors in working with Microsoft technologies aren't really related to the error that it says. Please left me your beneficial experiences. Thanks.

Update: The terse contents for ~/views/Account/Manage.cshtml file maybe useful:

@using Social.Models;
@using Microsoft.AspNet.Identity;

@{
    ViewBag.Title = "manage";
}

<div class="layout-app">

    <div class="row row-app margin-none">

        <div class="col-md-12">

            @if (ViewBag.HasLocalPassword)
            {
                 @Html.Partial("_ChangePasswordPartial")
            }
            else
            {
                 @Html.Partial("_SetPasswordPartial")
            }
        </div>
    </div>
</div>

Solution

  • I misused ViewBag in master layout file to consume in other pages. My structure made ViewBag as a required field so I had to instantiate it before. But I forgot to instantiate it which caused to fire such this error and it seems to be irrelevant to Scripts.Render.
