Visual Studio 2022 MVC Object Reference Error with @Script.Render(~/bundles/bootstrap)-CodePudding

I'm a beginner college student working on a group project in MVC. Things had been going relatively well until our most recent code update.

When testing the app (locally) in browser, the app throws this error:

Object Reference Error

Stack trace:

I believe this is either an issue with BundleConfig.cs file or the Bootstrap.js file. I'm not entirely sure where or how to even look for the root cause.

I've looked around this site at similar questions and a common solution was to change

 bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js"));

 bundles.Add(new Bundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js"));

That stopped the exception from happening, but the bootstrap elements were gone.

After

I've been hitting my head against a wall trying to find out what's going on.

CodePudding user response：

So someone on the team must have updated Bootstrap and jQuery. Our project template did not like that. I went ahead and downgraded to the default Bootstrap and jQuery versions that came with the ASP.Net Web App (.net Framework) template and that fixed the issue.

Though I am curious in learning how to maybe address this issue without having to downgrade.

Happy to say though, that the project is up and running.
