I successfully realized the login service at my own project using MongoDB. But I didn't use video tutorial you pointed out.

It looks like you have an error in your configuration file. I would first check the config for mongodb component. It must be something like following (yii2-mongodb project README)

return [
    //....
    'components' => [
        'mongodb' => [
            'class' => '\yii\mongodb\Connection',
            'dsn' => 'mongodb://developer:password@localhost:27017/mydatabase',
        ],
    ],
];

Other component is worth checking out is the user component:

return [
    //....
    'components' => [
    'user' => [
        'identityClass' => 'frontend\models\User', // This is your class with IdentityInterface
        'enableAutoLogin' => true,
        'identityCookie' => ['name' => '_identity-frontend', 'httpOnly' => true],
    ],
];

But in fact, similar error may appear for any configuration element of YII2.

as per video change below function behaviors in comman/models/User.php

 public function behaviors()
{
  return [
    'timestamp' => [
     'class' => 'yii\behaviors\TimestampBehavior',
    'attributes' => [
      ActiveRecord::EVENT_BEFORE_INSERT => ['created_at', 'updated_at'],
      ActiveRecord::EVENT_BEFORE_UPDATE => ['updated_at'],
        ]
    ]
  ];
}
