Does not work with Nest.JS webpack compiler

[HenryWu01]

Here is my webpack.config.js:

const transformer = require('ts-type-checked/transformer');

module.exports = function (options) {
    return {
        ...options,
        module: {
            rules: [
                {
                    test: /\.ts$/,
                    loader: 'ts-loader',
                    options: {
                        getCustomTransformers: (program) => ({
                            before: [transformer(program)]
                        })
                    }
                }
            ]
        }
    };
};

After many deprecated warnings, webpack build failed:
