[webpack-cli] Failed to load 'D:\Dev\metronicnet\blazon\blazor_demo1\Starterkit\_keenthemes\tools\webpack.config.js' config
[webpack-cli] ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and 'D:\Dev\metronicnet\blazon\blazor_demo1\Starterkit\_keenthemes\tools\package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.
