What could be wrong with webpack?

Question

Laravel

I deploy pure laravel 5.5 (the same with the project that is already running)
I do npm install, everything is fine. I do npm run prod/dev/watch and get the same error

> @ prod /home/docker/project
> npm run production


> @ production /home/docker/project
> cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.stats should be one of these:
   object { context?, hash?, version?, timings?, assets?, env?, colors?, maxModules?, chunks?, chunkModules?, modules?, children?, cached?, cachedAssets?, reasons?, source?, warningsFilter?, excludeAssets?, excludeModules?, exclude?, entrypoints?, errorDetails?, chunkOrigins?, modulesSort?, moduleTrace?, chunksSort?, assetsSort?, publicPath?, providedExports?, usedExports?, optimizationBailout? } | boolean | "none" | "errors-only" | "minimal" | "normal" | "detailed" | "verbose"
   Used by the webpack CLI program to pass stats options.
   Details:
    * configuration.stats has an unknown property 'errors'. These properties are valid:
      object { context?, hash?, version?, timings?, assets?, env?, colors?, maxModules?, chunks?, chunkModules?, modules?, children?, cached?, cachedAssets?, reasons?, source?, warningsFilter?, excludeAssets?, excludeModules?, exclude?, entrypoints?, errorDetails?, chunkOrigins?, modulesSort?, moduleTrace?, chunksSort?, assetsSort?, publicPath?, providedExports?, usedExports?, optimizationBailout? }
    * configuration.stats has an unknown property 'warnings'. These properties are valid:
      object { context?, hash?, version?, timings?, assets?, env?, colors?, maxModules?, chunks?, chunkModules?, modules?, children?, cached?, cachedAssets?, reasons?, source?, warningsFilter?, excludeAssets?, excludeModules?, exclude?, entrypoints?, errorDetails?, chunkOrigins?, modulesSort?, moduleTrace?, chunksSort?, assetsSort?, publicPath?, providedExports?, usedExports?, optimizationBailout? }
    * configuration.stats should be a boolean.
    * configuration.stats should be one of these:
      "none" | "errors-only" | "minimal" | "normal" | "detailed" | "verbose"

Google didn't help. Used by laravel-mix as an add-on for webpack.

UPD
webpack config

/**
 * As our first step, we'll pull in the user's webpack.mix.js
 * file. Based on what the user requests in that file,
 * a generic config object will be constructed for us.
 */

require('../src/index');
require(Mix.paths.mix());

/**
 * Just in case the user needs to hook into this point
 * in the build process, we'll make an announcement.
 */

Mix.dispatch('init', Mix);

/**
 * Now that we know which build tasks are required by the
 * user, we can dynamically create a configuration object
 * for Webpack. And that's all there is to it. Simple!
 */

let WebpackConfig = require('../src/builder/WebpackConfig');

module.exports = new WebpackConfig().build();
