Ошибка при интеграции темы в Yii 2 с базовым шаблоном приложения

Я пытаюсь интегрировать тему в Yii2. Я поместил тему в папку тем внутри основной папки. В файле config / web.php я вставил следующий код в массив компонентов.

  <?php

$params = require(__DIR__ . '/params.php');

$config = [
'id' => 'basic',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'components' => [
'request' => [
// !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
'cookieValidationKey' => 'bnfhxfasdf7324675@$%fg',
],
'cache' => [
'class' => 'yii\caching\FileCache',
],
'user' => [
'identityClass' => 'app\models\User',
'enableAutoLogin' => true,
],
'errorHandler' => [
'errorAction' => 'site/error',
],
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
// send all mails to a file by default. You have to set
// 'useFileTransport' to false and configure a transport
// for the mailer to send real emails.
'useFileTransport' => true,
],
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'db' => require(__DIR__ . '/db.php'),
'view' => [
'theme' => [
'basePath' => '@app/themes/flat',
'baseUrl' => '@web/themes/flat',
'pathMap' => [
'@app/views' => '@app/themes/flat/views',
],
],
],
],
'params' => $params,
];

if (YII_ENV_DEV) {
// configuration adjustments for 'dev' environment
$config['bootstrap'][] = 'debug';
$config['modules']['debug'] = [
'class' => 'yii\debug\Module',
];

$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
'class' => 'yii\gii\Module',
];
}

return $config;

Но я получаю ошибку

Unknown Property – yii\base\UnknownPropertyException
Getting unknown property: yii\web\Application::theme

в Component.php в

foreach ($this->_behaviors as $behavior) {
if ($behavior->canGetProperty($name)) {
return $behavior->$name;
}
}
}
if (method_exists($this, 'set' . $name)) {
throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
} else {
throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
}

Ниже приведена трассировка стека из файла app.log.
