ActiveController don't works.

I'm trying to follow along this official guide

I have User and UserController. Please, take a look on my code:

<?php

namespace api\controllers;

use yii\rest\ActiveController;

/**
 * Class UserController
 *
 * @package api\controllers
 */
class UserController extends ActiveController
{
    public $modelClass = 'api\models\User';

}

and User model:

<?php

namespace api\models;

class User extends \yii\db\ActiveRecord
{
    /**
     * {@inheritdoc}
     */
    public static function tableName()
    {
        return '{{%user}}';
    }
}

My configuration (config/main.php)

<?php
$params = array_merge(
    require __DIR__ . '/../../common/config/params.php',
    require __DIR__ . '/../../common/config/params-local.php',
    require __DIR__ . '/params.php',
    require __DIR__ . '/params-local.php'
);

return [
    'id' => 'app-api',
    'basePath' => dirname(__DIR__),
    'language' => 'ru-RU',
    'bootstrap' => ['log'],
    'controllerNamespace' => 'api\controllers',
    'components' => [
        'request' => [
            'parsers' => [
                'application/json' => 'yii\web\JsonParser',
            ]
        ],
        'response' => [
            'class' => 'yii\web\Response',
            'format' => 'json'
        ],
        'user' => [
            'identityClass' => 'common\models\User',
            'enableAutoLogin' => true,
            'identityCookie' => ['name' => '_identity-frontend', 'httpOnly' => true],
        ],
        'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                ],
            ],
        ],
        'urlManager' => [
            'enablePrettyUrl' => true,
            'enableStrictParsing' => true,
            'showScriptName' => false,
            'rules' => [
                [
                    'class' => 'yii\rest\UrlRule',
                    'controller' => 'user',
                ],
            ],
        ],
    ],
    'params' => $params,
];

How I start it? Simple. Just with the help of $ php -S localhost:8900 inside the web directory. But when I visit localhost:8900/users I see the following:

{"name":"Not Found","message":"Page not found.","code":0,"status":404,"type":"yii\web\NotFoundHttpException","previous":{"name":"Invalid Route","message":"Unable to resolve the request \"user/index\".","code":0,"type":"yii\base\InvalidRouteException"}}

I have tried to start it via docker: Here is my docker-compose:

version: '3.2'

services:

  api:
    build: api
    ports:
      - 22080:80
    volumes:
      # Re-use local composer cache via host-volume
      - ~/.composer-docker/cache:/root/.composer/cache:delegated
      # Mount source-code for development
      - ./:/app

  frontend:
    build: frontend
    ports:
      - 20080:80
    volumes:
      # Re-use local composer cache via host-volume
      - ~/.composer-docker/cache:/root/.composer/cache:delegated
      # Mount source-code for development
      - ./:/app

  backend:
    build: backend
    ports:
      - 21080:80
    volumes:
      # Re-use local composer cache via host-volume
      - ~/.composer-docker/cache:/root/.composer/cache:delegated
      # Mount source-code for development
      - ./:/app

  mysql:
    image: mysql:5.7
    environment:
      - MYSQL_ROOT_PASSWORD=verysecret
      - MYSQL_DATABASE=yii2advanced
      - MYSQL_USER=yii2advanced
      - MYSQL_PASSWORD=secret
      - MYSQL_ROOT_HOST=%
    ports:
      - 3306:3306

and Docker file:

FROM yiisoftware/yii2-php:7.2-apache

# Change document root for Apache
RUN sed -i -e 's|/app/web|/app/api/web|g' /etc/apache2/sites-available/000-default.conf

I run it via docker-compose up -d. And when I visit localhost:22080/users I see the same like with running via embedded php dev server.

So, where I wrong? Where is the problem?

Update

Ok, after some research I have found, that the crash is happening here :

   /**
     * Creates a controller based on the given controller ID.
     *
     * The controller ID is relative to this module. The controller class
     * should be namespaced under [[controllerNamespace]].
     *
     * Note that this method does not check [[modules]] or [[controllerMap]].
     *
     * @param string $id the controller ID.
     * @return Controller|null the newly created controller instance, or `null` if the controller ID is invalid.
     * @throws InvalidConfigException if the controller class and its file name do not match.
     * This exception is only thrown when in debug mode.
     */
    public function createControllerByID($id)
    {
        $pos = strrpos($id, '/');
        if ($pos === false) {
            $prefix = '';
            $className = $id;
        } else {
            $prefix = substr($id, 0, $pos + 1);
            $className = substr($id, $pos + 1);
        }

        if ($this->isIncorrectClassNameOrPrefix($className, $prefix)) {
            return null;
        }

        $className = preg_replace_callback('%-([a-z0-9_])%i', function ($matches) {
                return ucfirst($matches[1]);
            }, ucfirst($className)) . 'Controller';
        $className = ltrim($this->controllerNamespace . '\\' . str_replace('/', '\\', $prefix) . $className, '\\');
        // THE PROBLEM IS HERE !!! WITH THE  !class_exists($className)
        if (strpos($className, '-') !== false || !class_exists($className)) {
            return null;
        }

        if (is_subclass_of($className, 'yii\base\Controller')) {
            $controller = Yii::createObject($className, [$id, $this]);
            return get_class($controller) === $className ? $controller : null;
        } elseif (YII_DEBUG) {
            throw new InvalidConfigException('Controller class must extend from \\yii\\base\\Controller.');
        }

        return null;
    }

the !class_exists($className) takes this string as argument "api\controllers\CategoryController" and returns true. The condition works, and I have null as result.

What is happening then? The following:

    /**
     * Runs a controller action specified by a route.
     * This method parses the specified route and creates the corresponding child module(s), controller and action
     * instances. It then calls [[Controller::runAction()]] to run the action with the given parameters.
     * If the route is empty, the method will use [[defaultRoute]].
     * @param string $route the route that specifies the action.
     * @param array $params the parameters to be passed to the action
     * @return mixed the result of the action.
     * @throws InvalidRouteException if the requested route cannot be resolved into an action successfully.
     */
    public function runAction($route, $params = [])
    {
        $parts = $this->createController($route);
        if (is_array($parts)) {
            /* @var $controller Controller */
            list($controller, $actionID) = $parts;
            $oldController = Yii::$app->controller;
            Yii::$app->controller = $controller;
            $result = $controller->runAction($actionID, $params);
            if ($oldController !== null) {
                Yii::$app->controller = $oldController;
            }

            return $result;
        }

        $id = $this->getUniqueId();
        throw new InvalidRouteException('Unable to resolve the request "' . ($id === '' ? $route : $id . '/' . $route) . '".');
    }

I see the familiar exception InvalidRouteException. Any ideas?
