Error: TypeScript emitted no output for /frontend/src/index.tsx

При компиляции webpack получаю такую ошибку:

Вот мой webpac.config.js

module.exports = {
    mode: "production",
    entry: './src/index.tsx',
    resolve: {
        // Add '.ts' and '.tsx' as resolvable extensions.
        extensions: [".ts", ".tsx", ".d.ts"]
    },
    module: {
        rules: [
            {
                test: /\.ts(x?)$/,
                exclude: /node_modules/,
                use: [
                    {
                        loader: "ts-loader"
                    }
                ]
            },
            {
                enforce: "pre",
                test: /\.js$/,
                loader: "source-map-loader"
            }
        ]
    },
    externals: {
        "react": "React",
        "react-dom": "ReactDOM"
    }
};

Вот tsconfig.json
