MVC Bundling - Failed to load resource

RobVious picture RobVious · Aug 24, 2013 · Viewed 28.8k times · Source

What could be causing this? I'm working with a DurandalJS project that builds and runs locally just fine. When I try to deploy to an Azure Website, the app publishes but fails in the browser with:

Failed to load resource: the server responded with a status of 404 (Not Found) http://appsite.azurewebsites.net/Scripts/vendor.js?v=KJCisWMhJYMzhLi_jWQXizLj9vHeNGfm_1c-uTOfBOM1

I haven't customized any of the bundling.

my bundle configs:

public class BundleConfig
{
    // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkId=254725
    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                    "~/Scripts/jquery-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                    "~/Scripts/jquery-ui-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/Scripts/jquery.unobtrusive*",
                    "~/Scripts/jquery.validate*"));

        // Use the development version of Modernizr to develop with and learn from. Then, when you're
        // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                    "~/Scripts/modernizr-*"));

        bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

        bundles.Add(new StyleBundle("~/Content/themes/base/css").Include(
                    "~/Content/themes/base/jquery.ui.core.css",
                    "~/Content/themes/base/jquery.ui.resizable.css",
                    "~/Content/themes/base/jquery.ui.selectable.css",
                    "~/Content/themes/base/jquery.ui.accordion.css",
                    "~/Content/themes/base/jquery.ui.autocomplete.css",
                    "~/Content/themes/base/jquery.ui.button.css",
                    "~/Content/themes/base/jquery.ui.dialog.css",
                    "~/Content/themes/base/jquery.ui.slider.css",
                    "~/Content/themes/base/jquery.ui.tabs.css",
                    "~/Content/themes/base/jquery.ui.datepicker.css",
                    "~/Content/themes/base/jquery.ui.progressbar.css",
                    "~/Content/themes/base/jquery.ui.theme.css"));
    }
}

DurandalBundleConfig:

public class DurandalBundleConfig {
public static void RegisterBundles(BundleCollection bundles) {
  bundles.IgnoreList.Clear();
  AddDefaultIgnorePatterns(bundles.IgnoreList);

  bundles.Add(
    new ScriptBundle("~/Scripts/vendor.js")
        .Include("~/Scripts/jquery-{version}.js")
        .Include("~/Scripts/jquery-ui-{version}.js")
        .Include("~/Scripts/bootstrap.js")
        .Include("~/Scripts/knockout-{version}.js")
        .Include("~/Scripts/knockout.mapping-latest.js")
         .Include("~/Scripts/isotope.js")
          .Include("~/Scripts/toastr.js")
          .Include("~/Scripts/tag-it.js")
    );

  bundles.Add(
    new StyleBundle("~/Content/css")
      .Include("~/Content/ie10mobile.css")
      .Include("~/Content/app.css")
      .Include("~/Content/bootstrap.min.css")
      .Include("~/Content/bootstrap-responsive.min.css")
      .Include("~/Content/font-awesome.min.css")
      .Include("~/Content/durandal.css")
      .Include("~/Content/starterkit.css")
       .Include("~/Content/toastr.css")
       .Include("~/Content/tag-it.css")
       .Include("~/Content/zen-theme.css")
    );
}

public static void AddDefaultIgnorePatterns(IgnoreList ignoreList) {
  if(ignoreList == null) {
    throw new ArgumentNullException("ignoreList");
  }

  ignoreList.Ignore("*.intellisense.js");
  ignoreList.Ignore("*-vsdoc.js");
  ignoreList.Ignore("*.debug.js", OptimizationMode.WhenEnabled);
  //ignoreList.Ignore("*.min.js", OptimizationMode.WhenDisabled);
  //ignoreList.Ignore("*.min.css", OptimizationMode.WhenDisabled);
}
} 

In my html page I use this:

@Scripts.Render("~/Scripts/vendor.js")

This is preventing required libraries (like knockout) from loading. Could it be something in my web.comfig? Any tips would be awesome.

UPDATE:

I can reproduce the exact issue locally if I do the following:

new ScriptBundle("~/Scripts/vvendor.js")  // change the virtual output directory here

I think this means the view can't find the directory when it's published for some reason...

1. Do not use file extensions in bundle names

As Brett mentions, you should not have a file extension in your bundle name.

The reason for this is that IIS routing will assume the request is for a file if an extension is present.

2. Do not use folder paths as bundle names

Note: This does not occur in development, so may only bite you when you deploy to production

The second thing to avoid is having bundle names that match the name of a real folder in your project/website. IIS will match a physical folder before it resorts to the bundle routing.

e.g. if you have a /Content/Login folder for your login page styles, you cannot use a bundle called ~/Content/Login. IIS will see the physical folder and assume it is a directory browse request (you will likely get a 403 error from Azure servers).

Suggested naming:

Suggest you use the name bundle in all bundles, to avoid a directory clash, and include css as well. Do not ever have a folder called bundles in your project (because of issue 2 above).

Example bundle names:

  • "~/bundles/jquery"
  • "~/bundles/addins"
  • "~/bundles/css"
  • "~/bundles/css/login"
  • "~/bundles/css/bootstrap"

etc
