NestJS couldn't log some class names

in NestJS, when I start app app in production mode (so by using obfuscated js file), it logs class names as _0x.....

Examples:

• PrimaryDbContextModule -> _0x23db20
• AppModule -> _0x202e0a
• LoggerModule -> _0x2e3cc7

Expected Behavior

Current Behavior

Steps to Reproduce

webpack.config.js

const WebpackObfuscator = require('webpack-obfuscator');

module.exports = function (options)
{
    return {
        ...options,
        devtool: 'inline-source-map',
        plugins: [
            new WebpackObfuscator({
                rotateStringArray: true,
                sourceMap: true,
                optionsPreset: 'high-obfuscation',
                disableConsoleOutput: false,
            }, [])
        ]
    }
}
