react-scripts don't work after src/ directory renamed

Question

I renamed src/ to frontend/ and after this I have it searching in old folder src/:

$ npm run build

> [email protected] build
> react-scripts build

Could not find a required file.
  Name: index.js
  Searched in: /home/porton/Projects/passport_client_dfinity/src

despite I have created webpack.config.js:

const path = require('path');

// webpack.config.js
module.exports = {
    entry: './frontend/index.js',
    resolve: {
        modules: [path.resolve(__dirname, 'frontend'), 'node_modules'],
    },
};

Here is package.json:
