System.web.optimization bundle breaks with Kendo 2021.2.616

[Gerardo]

Hi, we recently upgraded from kendo 2020 to 2021.2.616.

We use System.web.optimization to bundle resources, when building Debug configuration all works fine because bundling is disabled, however when building the Release configuration the bundle is missing some javascripts files, I can't figure out which ones. 

This is the bundle definition:

RegisterScriptBundle(bundles,"~/scripts/libraries",
                        "~/Scripts/jquery-1.12.4.min.js",
                        "~/Scripts/kendo/2021.2.616/kendo.all.min.js",
                        "~/Scripts/kendo/2021.2.616/kendo.aspnetmvc.min.js",
                        "~/Scripts/kendo/2021.2.616/cultures/kendo.culture.en.min.js",
                        "~/Scripts/jquery.unobtrusive-ajax.min.js",
                        "~/Scripts/jquery.knob.min.js",
                        "~/Scripts/kendo.web.ext.js",
                        "~/Scripts/jquery.charcounter.js",
                        "~/Scripts/jquery-ui-1.12.1.min.js");

The javascript error is:

Uncaught TypeError: r.clone is not a function

prettyfied related code: 

 looks like related to SVG, but how to know which files to include?

[Gerardo]

it was not a dependency missing, looks like the minification performed by web.optimization package is altering the already minified kendo.all.min.js

I turned off that optimization (https://stackoverflow.com/a/21167876), just do the bundling and the problem was fixed.

Hello,

I'm glad that you managed to resolve the issue with bundling Kendo scripts. As an additional resource you could check the following sample project which demonstrates using ASP.NET bundles with KendoUI:

https://github.com/telerik/ui-for-aspnet-mvc-examples/tree/master/general/KendoAspNetBundles/KendoAspNetBundles 

Do not hesitate to write back, should you have other questions related to configuring Kendo widgets in your project.

Misho
