There is a ~/bundles/bootstrap in BundleConfig, which references ~/Scripts/bootstrap.js which is also there.
Is this a valid argument for "never update your modules"?
In Boundle.Config instead
bundles.Add(new ScriptBundle("~/bundles/mybundle").Include(
try
bundles.Add(new Bundle("~/bundles/mybundle").Include(

Hi @Bryan Valencia ,
How do you write in the BundleConfig? Maybe you could check your BundleConfig.You could change ScriptBundle to Bundle.Just like this:
bundles.Add(new Bundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js"));

I am having the same issue, have tried all the above fix actions...still have the same problem described.
Anyone get this one solved?
To perform minimization the bundler must parse the files. The error means there is a syntax error in the input files to the bundler.
note: you could detect the offending file by removing one at a time.
also check that you have the latest nuget package for web grease, so that it supports the latest syntax,
Hello team,
I used the default ASP.NET MVC C# template in visual studio.
The template use the boostrap v3. The migration is ok until to v4.6.1.
After the v5, @Scripts.Render generates an exception.
I try to rollback only bootstrap.js file, i don't have exception. The problem is link with content of file.
I try to change ScriptBundle by Bundle. I don't have exception.
Now, i rebuild the application and cleanup the cache of navigator. The display page is not good.
Devtools send an error on loading of bootstrap.min.js.map.
DevTools n’a pas pu charger le mappage de source : Désolé... Nous n’avons pas pu charger du contenu pour https://xxx.domain.fr/bundles/bootstrap.min.js.map:Erreur HTTP : code de statut 404,net::ERR_HTTP_RESPONSE_CODE_FAILURE
I think, it is necessary to review the NuGet package.
For the moment, I canceled the migration.
What can I change?
Happy new year,
Mick
