What is yii2 complaining about?

Question

Yii

I run cron and get this error:
root:/var/www/wokster/data/yii# php yii mail/fly
PHP Fatal error: Uncaught exception 'yii\base\UnknownPropertyException' with message 'Setting unknown property: yii\console\ ErrorHandler::errorAction' in /var/www/wokster/data/yii/vendor/yiisoft/yii2/base/Component.php:197

What could be the reason?

I asked myself, I will answer.
The problem is, don't mess with common/config
'errorHandler' => [
'errorAction' => 'site/error',
],
