Bundler & Minifier generating "Object reference not set to an instance of an object" error

I trying bundle and minify my CSS and JS files in ASP.NET Core 3.0 with BuildBundlerMinifier.Core. Also Installed Bundler & Minifier extension for Visual Studio 2019.

When I try Debug the project, it working correctly without error but when I rebuild it, I'm getting the following error;

Object reference not set to an instance of an object

I don't get an error when restart Visual Studio and I can debug the project again but If I rebuild it again, I'm getting the error.

It's bundleconfig.json file

[
  {
    "outputFileName": "wwwroot/assets/css/style.bundle.min.css",
    "inputFiles": [
      "wwwroot/assets/plugins/global/plugins.bundle.css",

Visual Studio, Bundler & Minifier extension, BuildBundlerMinifier and BuildBundlerMinifier.Core are up to date How can I fix it ?

Solution

  • The project has BuildBundlerMinifier and BuildBundlerMinifier.Core. I removed BuildBundlerMinifier from nuget and now it works.
